Swelling and inflammation on glans penis

I have got a mild swelling, inflammation, itching and irritations on glans penis from last month (30 to 40 days ago). Neither of the symptoms are permanent, it appears and relieves on its own. The inflammation and swelling is not confined to particular spot on glans penis sometime it appears on the tip another time underneath.          Warm sline water bath helps in relieving above symptoms. I also have had nail fungus (2 to 3 months ago) in middle finger that cleared up after applying 2% myconazole cream and frequent warm saline water dipping. I have tried (as per pharmacists friends suggestion) Candid Cream and Candid B Cream, have also taken 150 gm Fluconazole single oral dosage but the symptoms persists.  Earlier I also experienced  clear watery urethral discharge, mild discomfort in testicles which cleared up after I took azithomycin 1 gm and cefixime 400 mg single dosage. My partner also have infrequent itching and white discharge related problem. Suggest me.
