My 9 year old daughter has a rough red veiny rash that is tender to the touch on her collar bone and neck. At first I thought it was sunburn, but now I think maybe it is a result of being in a hot tub with the temperature too warm at a party. It burned when I applied Benadryl cream. Thoughts on what it could be?
Hi. It can be a skin burn or allergic reaction. So for a confirmation consult a Pediatrician and get evaluated. For now do cool compresses over the area. It will help in reducing inflammation and redness. Avoid exposure to heat and other irritants. Oral Ben Chat Doctor.  Please let me know if I can assist you further. Regards.
