As a final update to this and other discussions that I’ve written on on this forum.
Firstly, I’m not sure if I’m still in the correct section heading. What started out as a back problems seamed to evolve into something much more serious, Though saying that, It was a back problem to start with, but probably near the high end of the serious scale. Just going by the symptoms that I experienced the problem also seemed very similar to fibromyalgia and the treatments that I used seemed to parallel some alternative treatments used for cancer, though, it seems that if you don’t get an official diagnosis then its not possible to have something. So I seem to be stuck with the official diagnosis of sciatica.
Anyway, whatever it was, here is my final draft of my techniques and treatments to become well again. I avoided pharmaceutical drugs (fluconazole) in the later stages as the side effects were not too good and I discovered what seemed to be a less aggressive and more natural alternative.
Firstly, the best thing that I discovered was that basic old fashioned soap is the best and simplest treatment for tumour like things near the skin surface and deeper. The reason being, as I understand, is that opaque bar soap is alkaline and by applying it to the skin it reduces the acidity level of the skin and destroys infections.
Also, Think of soap as a preventative treatment. Glycerin soap is not the same as traditional soap and I avoided soap with propylene glycol as an additive. Soap with minimum ingredients is best.
Soap seems particularly good at relieving muscle pains and fibromyalgia type pains when left on the skin surface for 20 minutes or so.
What was really very surprising and affirming was that on reading the ingredients of soap I discovered that the main ingredients were coconut oil and palm oil. As in 'cocoate and palmate' More on palm oil later.
For correct use of soap think 'Turkish bath' ie apply to skin, leave for several minutes and rinse. That's probably the most important lesson I've learn't from this whole escapade. There should really be instructions on a bar of soap. Also, it really isn't very good under a shower, as the soap is rinsed immediately and has no time to be effective.
The following is my food method to get rid of tumour like things and other associated problems and joint problems.
A strict diet of.
Red meat, eggs, Block rye bread (100% rye), Rye biscuits, Oak cakes (ideally without sunflower oil), Lots of Spinach and Kale (at least 200g per day), onions, porridge, soya milk, Raisins, sultanas, berry fruits (black and blue and others probably) , limes, coconut milk 75%, tahini, peanut butter(cheap variety, with palm oil), Nuts (most types) but not too many brazils, a little beer (with minimum sugar content),
Oils - Coconut and unrefined palm oil.
Herbs and spices - Most types but particularly Oregano/oregano oil and chilly powder.
I only consumed things that I knew the ingredients of, or were organic.
Unrefined palm oil seems to have similar properties to coconut oil but much more effective.
Things that I avoided for the duration of the illness, though I can tolerate these things now to some extent.
Sugar and processed foods particularly.
All tree fruits. Peaches, plums, oranges, lemons etc etc, with the exception of limes and bananas and a few apples.
Anything that would be acidic, like pineapple, lemons and oranges.
Sunflower oil, where possible.
Alcohol, mostly. Wine in particular.
I avoided alcohol sugar substances like propylene glycol because I experienced a very serious elevation of the problem from getting this substance on my hands in the workshop. (it seemed to be absorbed very easily through the skin)
As I understand, Propylene glycol is metabolised into an acid in the body, which could be the reason for such a bad reaction.
I avoided tooth paste also. Propylene glycol is present in some toothpaste, leading to delayed head aches, dizziness and lack of concentration. and also processed foods, cosmetics and some soaps.
I also avoided similar sounding substances also, as a precaution. For no other reason other than they sound similar. Polypropylene glycol (PPG), polyethelene glycol (PEG). for example. I’m also very suspicious of glycerin, but this may be because it generally includes propylene glycol.
Simple food treatments
The following recipe is the most efficient treatment that I've discovered to date. I’ve tested it over several months and it works incredibly well.
It seems like an alternative to fluconazole but much less aggressive and with no obvious side effects, It seems to be very efficient and subtle.
It seems to reduce tumours, ease joint pains and makes one feel generally better.
Add a small glass of coconut milk (75% plus coconut) to a milk pan and place on a low heat. Add 1 level teaspoon of ground turmeric and 1/2 level teaspoon of unrefined palm oil. Simmer and stir for a minute or two. Pour into a glass and drink very slowly.
(Unrefined palm oil is used in african cooking mostly and is bright yellow/orange in colour. Same colour as a very effective soap).
I did this twice a day on an irregular basis. Perhaps for three days and then a week later for 3 days etc etc.
Add to this a 100g bar of high percentage (80% plus) chocolate every now and then ( maybe one or two a week) and additionally, jars of peanut butter with extra added unrefined palm oil (1 teaspoon) and sometimes turmeric and often raisins.
Note: The chocolate and peanut butter does have a small amount of sugar, which I could deal with during the recovery stage of the illness. I would have avoided any sugar in the really bad stages.
In these simple ingredients and combinations I found all the help that I needed.
Side effects to date.
From taking coconut - It seems that when I take coconut now my near vision eyesight becomes a bit blurred. This clears up when I stop talking it. My eye sight is far better than a few years ago.
From eating peanut butter ( one small jar a day for several days) - This can give me some pain to my kidneys which stops when I stop eating it. The benefit seemed to out weigh the discomfort. Though It was a calculated gamble which seems to have paid off.
Loss of short term memory for a few weeks after taking Turmeric/coconut/palm oil mix. Memory has returned to normal now and no further problems.
I've not mentioned it previously, but I also had terrible pains in my lungs. I think this was a knock on from the problem/tumour I had in my back and spine.
I dealt with this by inhaling the vapour from heated oregano oil.
I would put 4 drops of oregano oil/olive oil mix into a cup of boiling water and carefully inhale a small amount of the vapour. I cant express too much how strong the oregano oil is. It's very caustic and can burn in high concentrations. One or two inhalations over a day or two seemed enough to ease the problems and pain.
Or alternatively, just put lots of dried oregano in your food and breath the vapours.
Also, the vapours of oregano oil are very good about the house, to kind of fumigate the living spaces. Again, not much is needed.
Oregano and olive oil mix also seems to be the most effective treatment for Onychomycosis. Going back a few years I applied it sparingly under the nail once a week until it was cleared up and it never returned. The nail must be very dry, so it can be absorbed fully. It did sting a bit as I remember.
In brief conclusion. (and in my opinion)
The causes were. (over the past 30 years)
1. The introduction of showers (making soap non effective) and leading to a less effective alternative to soap.
2. Badly designed bedding/mattresses using inappropriate materials.
The exacerbating factors were.
1. Penicillin based antibiotics
2. Sugars and sugary substances, particularly propylene glycol.
The preventative solution is.
1. Soap and the correct use of soap.
2. Well designed bedding with a changeable barrier layer over the mattress.
3. Careful use of antibiotics
4. Avoidance of certain food and product additives
Hope its helpful, Is taken eight years of helliish times to get here, but it all seems to have worked out fine, eventually.
I have broken my coccyx and apart from needing to sit on a cushion when driving or at work, it had very little impact. I then suffered a slip-fall when on holiday in Majorca which started back flare-ups once again. I then suffered from a herniated L5 onto S1 which caused pro-longed and agonising sciatica which refused to respond to drugs or a spinal epidural. I was on huge doses of Tramadol, Gabapentin and Diclofenac which did little to relieve either the spasms or the pain. The micro-disectomy I had in Dec 2012 was brilliant and apart from the obvious initial recovery and physio, I remained pain free, until I started getting recurring bouts of sciatica in June 2013. I was sent for an MRI which showed that the remaining part of L5 had prolapsed, along with L4. That was in September 2013. The referal back to the Consultant was sent on the 10 Oct 2013 but somehow got lost so it wasn't until May this year that I saw him again. Unfortunately, there is a significant narrowing which is putting pressure on the S1 nerve but the pain is different and the loss of sensation in my foot and leg have been a totally new experience. Have trained myself to look at my foot so that the brain connects to that fact before standing as have suffered a number of 'splats' 
The word 'Spondylolisthesis' was being used & didn't really know much about it until, like you, I did my research. It was an easy diagnosis from that point! Have had a guided HC injection into the hip and another spinal epidural, neither have been effective although there was a slight improvement in the consistency of the numbness in my foot. Having now had the standing/flex x-rays, it has shown a significant slippage of the vertebrae with the prolapsed discs adding to the fun. Have had the weekend to think about things, discuss with family etc. and, following these and a little more research, am opting to have the surgery. This is not a case of 'wanting' surgery, it is a case of favourable factors now rather than putting it off & suffering muscle degenaration and progressive loss of mobility. I am not kidding myself as I know this is 'major' surgery with medical 'Mechano', lamination etc'. but, as the Consultant has told me that I will have 75% immediate pain relief following the recovery period of 4-6wks, I'd rather have the surgery now with age and relative fitness being on my side!
