Thanks a lot for your answer.
My health issues started at the age of 14: Nasal congestion/clogging, frequent throat infections, Rosacea, constipation; I believe all of these health issues are strongly related; I have been suffering from all of these ever since; no doctor (MD) in Turkey/USA was able to help me with any of these problems. 1.5 years of weekly allergy shots (to desensitize my body against allergens) had zero effect on my sinuses.
Since the age of 14 (I am 45 now which means I have been on nasal sprays for the last 30 years) I have been on nasal sprays of all sorts including corticosteroid ones; have been a heavy user of OTC nasal sprays and have been on Oximetazoline HCL (4 to 5 times a day; have to use my spray when waken up by clogged nose every night; never had a sleep longer than 4 hours since I was 14) for the last 10 or so years. Even a 30 seconds of cigaret smoke exposure or exposure to home/street dust would send me into a full-blown Pharyngitis which develops in the next 2-3 hours. Many times every year I had to resort to antibiotic treatments which led to 20days of heavy drug use most of the cases. My nose is always in bleeding state which is visible when I blow my nose. My Rosacea gets worse with certain foods such as hazelnut which lends support to my idea that IBS (IrritableBowelSydrome) might be the cause of my problems.
I was in HoffmanEstates-ILLINOIS; worked there 3 months in 2012 and my nasal congestion and clogging was the same but after 3 months I left my job and spent 30 days without working; in this last month my nasal congestion and clogging got significantly less; so much so that I was taking nasal spray only before bed as a caution to sleep better (nasal clogging wakes me up); considering 30 years of history of nasal congestion/clogging, this improvement was an absolute miracle. The interesting thing is that the situation went on during the next 5 months I spent jobless in Turkey. This made me start thinking that the stress from my job leads to constipation and IBS (IrritableBowelSyndrome) which causes undigested food particles to leak into blood stream causing my nasal congestion/clogging (no surprise my nasal congestion/clogging increases 4 times 5 minutes after I start eating, especially with foods like onion/garlic/radish) and Rosacea. At the end of this 6 months of joblessness I returned to the USA and my health issues started all over again and continued unabated; that 6 months remains to be the only period where I did not suffer from the 4 problems as much.
Just recently I found out that I have an enlarged liver. The wholistic doctor I visited a month ago in Chicago told me that I might be suffering from HepatitisB upon seeing my blood test (AntiHBs > 836positive) but this can also be due to the standard shots I received when I was a child.

I hope you can help or direct me to someone who can help.
God bless you.
