Mystery itchy bumps spreading for 7+ days, dermatologist unsure, please help
I’ve had the symptoms shown in the first two pictures (on my right leg only) for about 7 days. I initially assumed it was from sand, sweat, and sunscreen since we got back from a vacation in Italy on August 6th. About 9 days in, my boyfriend developed similar-looking bumps on his stomach.
On Monday I saw a dermatologist and she said it could be shingles (herpes zoster) or contact dermatitis, and prescribed Advantan cream and Aerius (desloratadine). It looked a bit better for a day, but since Tuesday I’ve gotten many, many more bumps all over my hands and legs (both, right and left). These new ones feel different: itchy AND painful.
I went back today and she added Xyzal (levocetirizine) on top of the Aerius. She said the bumps look like insect bites, so I checked the whole house for bed bugs and found nothing. Until tonight I hadn’t noticed much itching in the evenings, but tonight it suddenly got way worse.
What should I do at this point?
