Had Oral Sex. High Dose Of Cortisone. Can I Raise My Immunity Against Allergy?

I am 30 years old,I moved to Germany 2 years ago,after 6 months I started to have chronic health problems, last March I had 2 consequent flus then thrombosed Hemorrhoids ,I used many medications at that time: immunal to raise my immunity (Russian Medication), gelomyrtol, Faktu for the hemorrhoid problem,couple of days later,I developed severe allergy and I was on high dose of cortisone ,the hospital gave me an allergy report that I am allergic to immunal or gelomyrtol (which turned to be wrong because by mistake I took a similar medication yo immunal and didn t cause me any problems),6 months later I had a cyst in my intestines and they claimed I have Chlamydia after analyzing the lab sample,though I am still a virgin,I don t think oral sex can cause all of this however. I undertook an operation to remove the cyst,now I have diarrhea on and off and stomachache sometimes,and green vaginal discharges,they said that the bacterial balance in my vagina is not balanced,now I have again cold (I get cold every 3 months) and I have Mastitis and again thrombosed Hemorrhoids and the yellowish vaginal discharges and Diarrhea.What could be the reason possibly? any clue?
