Hello,
Since these bumps appeared after wearing the watch, so it can be due to allergic contact dermatitis. Take some oral antihistaminic like Benadryl and apply some calamine lotion or mild steroid cream on the rash. If the symptoms persist then please get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Thanks for the response.
Can anyone provide any additional comments or thoughts?
Could be contact dermatitis, but it usually does cause discomfort such as itching. They look like hives, which could reaffirm the allergic reaction scenario, but it could also be from pollen, dust, or other irritants.
