Prolonged mouth ulcer. Crp and somemed!

So, the problem is that from last 1 year I have been suffering from mouth ulcers and mouth sores. I consulted many doctors but didn't get desired results and in the end I consulted Gastroenterologist and It relieved me to some instance for 2.5 -3.5 months but since the beginning of rainy season my condition has become worse than ever all I see in my mouth is mouth sores and white skin peeling out from everywhere. I can't even describe the pain that I am feeling due to these cuts in my mouth and throat. I recently consulted with a rheumatologist after suggestion from some doctors now after I consulted with the doctor she prescribed me some steroids and kenacort gel but after 10 days It didn't make too much difference she also prescribed some tests like CBC,LFT,RFT,ESR,CRP ,ANA,HbsAg,HCV,HIV,anti PR3,AntiMPO by ELISA, And other test related to auto immune but all the reports were fine and I met her again and she told me that she thinks itis behcet disease and write hlab51,crp and somemed
