To fix the bump quickly, just do this...

Detailed Answer:
Dear XXXX,

Thanks for choosing healthcaremagic.com

I'm Dr. Neel Kudchadkar and I'll help you with this problem.

Thanks for sending us a picture of the "bump" on your arm.
I've examined the photograph carefully and I strongly think and feel it's either an insect bite or an allergic reaction (to say a nettle sting, and the like, or a food item that went badly against your system)

I'd love to give you a prescription, and I cannot do so over the internet, I'll very politely ask you to go to your favourite doctor and he or she will prescribe you,
some Levocetrizine tablets and Silver Sulfadiazine cream. The actual "brand names" may be different, but it'll get "all better" soon. The first medicine will stop the pain and swelling and the second medicine will heal the blister.

Dear XXXX, please take care of yourself.

Thanks again,
Dr. Neel Kudchadkar
