What causes large welts on back?
Patient: I was going to give my 4 year old son a bath...so took off his shirt to see 2 large welts on his back. At first, it look like someone hit him...but after looking more closely...they look like bites of some sort. They are quite large though...nothing like I have seen. I did have to pick him up from pre-school today with a stomache ache...could they be related? Doctor: hi, most likely these are insect bite. These are not related to stomach ache. insect bite results in itching, fever, and secondary infection. you can give anti allergic syrup containing hydroxyzine like syrup atarax to the child so that itcching can be relieved. an examination by doctor is necessary so that we may not miss any important finding. If there is secondary infections and antibiotic needs to be started. Take care.
