Hi I have high fever (goes up to 39.1C) for almost a month , accompanied by headache, mid and lower back pain, fatigue, depression and generally feeling very down. Nose is blocked, unless I take Clarinase. I have had surgery in the past for septum deviation . I ended up in ER for an injection to bring the temp down which it did, but a month later its all back. Have a horrible taste in my mouth. My gums and throat are also inflamed (in British , but living in Saudi Arabia at the moment. It s very dusty here and the ACs don t help. Do I have a sinus infection ? Oh I forgot mention my left eye is swelling at the bottom, like in conjunctivitis and is extremely painful especially when the eye is open and / or I go out. (Dusty environment here - I m sure that makes it worse.) I was given two courses of eye antibiotic drops for conjunctivitis recently but it s happening again. Thank you Asma
