<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, Ive been getting swelling seem to be insect bites especially on the face both right and left side, once i developed allergy and my complete face got swollen. Looked for the insect traces in the bed and couldnt find any. First attempt: left side of my face, right hand ring finger, right side of my face. Moreover my husband, baby and myself sleep on the same bed and only me getting this problem. Recently Ive been given Ferrous Fumarate as my Heamoglobin content was low. Will this have any relation to my problem?  <response>: Hellos you are having swelling over the face right and left side with finger also. Sharing same bed with baby and husband. The new Chat Doctor. e. iron preparation for elevation of hemoglobin. I want to tell you that this swelling is the side effect of ferrous fumarate. As I have noted in my so many patients that iron toxicity also causes pain in all over body with joints pain and swelling as in your case. Two options are there, 1 Either change the medicine or 2 take some anti allergy medicine. In my opinion consult your treating doctor and get his opinion. Good luck.
