I have the same problem.
Every single day, I'm all snotted up and it doesn't go away no matter how many times I blow my nose. Sometimes I have really itchy eyelids and I'm constantly sniffing and having to swallow the hard mucus at the back of my throat throughout the day. My nostrils really sting because I'm always blowing / rubbing my nose.
At first I thought it was hayfever and thought it'd be over within a couple of months. Then summer turned to winter and I didn't ask the doctor about it as I thought he'd just say it was a cold.
Two years later, I ask the doctor about it and he tells me it's probably a dust allergy and to get some nasal spray. My symptoms are worse in the morning, or when I lye on my bed in the evening. I've now ditched the nasal spray, because it did nothing other than taste horrible down the back of my throat. I'm now using antihistamines daily, also with no effect.
In the past couple of years, I've been very tired and run down, sometimes finding it difficult to get out of bed (impacting my attendance at work!), with cycles of extreme tiredness (most often after my period).
I've been looking into whether or not I'm iron deficient, and a couple of my blood tests came back 'slightly low', but I haven't had another one in a while, because I've been to the doctor so many times in the last year I've got paranoid that they think I'm a hypochondriac and don't want to go back just to be dismissed again.
I've also been suffering from bloating after eating, and gas. On my last visit to the doctor I asked if it all tied together (my allergy symptoms, fatigue and stomach) and maybe I have a wheat intolerance? The doctor also dismissed this suggestion. I think he thought I meant a more extreme allergy, even though I specifically only said 'intolerance'.
Jason7 and Evelyn1979, I don't get the 'very sweet flowery taste' when I blow my nose, just the ongoing allergy symptoms and forever blocked nose.
In regards to the symptoms, I think I'm going to try to alter my diet, eliminate all wheat and eat more anti-allergy, anti-inflammatory foods.
Does anyone else have any suggestions?
