What causes red welts on legs?
Patient: Baby wakes up with welt on legs,red about 1/2 inch. During the day They turn a yellow color, then ooze and scab. Happened about three times in last month. First two times only one, last week three on same leg. Took her to doctor first time, told us could be bug bite and gave her Benadryl. Cleaned room, sheets, everything, second one about a week later. This time a couple of weeks between. Any suggestions? Doctor: Hi...I feel that your doctor is 100% right. This looks like an insect bite allergy only. Anti- allergic medication like Benadryl is appropriate. Once this starts there can be a phenomenon called second crop where in the allergy may manifest again with 1-2 weeks time. But the ooze which you are describing is due to secondary bacterial infection which your kid is getting. She might require a oral antibiotic like Cephalexin or Clindamycin. I suggest you to  consult your doctor for this prescription after he feels this suggestion is right.Regards - Dr. Sumanth
