Hi, I've 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 couldn't 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 I've been given Ferrous Fumarate as my Heamoglobin content was low. Will this have any relation to my problem?
