Why am I having hive like rash on my hand only?

Question

Hello doctor,

I am 25 years old female with no other symptoms. I had this hive like rash appear on the top of my right hand only. Has not spread, just gotten a deeper red color. Has some scab like areas I think because I scratched it at first. Does not itch anymore. Have not used any new products or exposed to any allergens. I am aware of to cause this. Again, only on my right hand. This is the fourth day of this rash. Have no idea what it could be from. I have taken Benadryl once daily, it had no effect. Also, have applied Hydrocortisone with no effect. Please help.

Hi,

I am glad you chose icliniq for your medical-related queries.

I understand your concern and will try to help you with it.

I have gone through your case. In my opinion, you have got an allergic reaction to something like it could be an insect bite or it could be some reaction to wild plants or weeds. It is good that you have used Hydrocortisone, and I will recommend you use it for another week. Apply two times a day for next seven days. And now about brown or black pigmentation. Then remember that it is a natural response of our skin to heal or combat any trauma with hyper or hypopigmentation. In your case, there is hyper pigmentation. Leave it as such right now. Because any creams, if used right now, will start itching and redness. And your lesions are fresh, so I do not recommend it right now. Either this will lighten itself with time or if required we will try at least after 14 days.

Thank you for consulting me.
