I had extreme pain and diahorea. Turned out afdter a number of emergency admission etc...I had been incoorectly treated for diverticulitis (I didn't have it) and the antibiotics had created Clostridium difficile infection, which was antibiotic resistant. After a long nightmare of more antivbiotics, getting sicker, huge pain occasionally...Vancomycin for ten days and Sacaromycae Boulardii probiotic for one month sorted it out.
Then gastritis which had eroded my oesophagus was diagnosed. I raised the head of my bed by putting bricks under the legs.
Stopped coffee, drank water in samll glasses and not a lot at a time, no food or drinks 3 hours before bed.
Left with IBS.Gastroenterologist #2 recommended mint oil capsules and an herbal digestive liquid to take before meals. Searched the internet and found a list of the FODMAP diet foods...the IBS is barely bothering me now...night and day in just a fortnight!
Still taking the probiotic that protects against bad gut bugs (saccaromycae boulardii) and a broaad spectrum probiotic in addition. Eating only sourdough bread and lactose free milk.
I did it by reading a lot and searching for information on the internet and not giving up. Most of my solutions were ac taully very simple. Antibiotics actually created the ahrm I experienced and I will never take a broad spectrum again without knowing specifically what iti s treating.
I was allergic to the proton pumps, two of them, so that is why I had to keep searching and did things like raised my bedhead.
For piost nasal drip, I removed the carpet from my house (discovered I had an extreme dust mite allergy) and started moppingh the wooden floor with hot water, vbinegar and eucalyptus oil. Washed all bedding in hot water with a cap of eucalyptus oil in the water and dried in the sun. Made sure there was no dust mite in any of the stored clothing etc. Used saline nasal spray and a newer steroid spray that treats only the tissue that needs it, very clever designed med. Took antihistamines til it was under control and if it comes back.
The FODMAP list was very helpful...doctors didn't mention it to me...found it searching on the internet.
VERY counterintuitive but it worked for me. I am now down to about 3% of the pain levels I had six months ago. Just had to systematically keep on working through the symptoms and get the correct diagnosis and not give up or panic.
