What Causes A Lump On The Arm?

I notices a small lump on my arm which was red with like a pinprick sized white spot at the top of it a few days ago, I thought it was an insect bite. Whilst in the shower today it has now got a almost perfect red oval shaped circle covering it and is a little painful to the touch.

Hi, thanks for sharing your health concerns with HCM!
If I were your treating Doctor for this case of PAINFUL arm nodule, I would come up with only one and one possibility and that is an infected sebaceous cyst turned into an abscess!

I suggest you to go for an FNAC of the nodule for confirmation and to relieve your concerns; then revert back to us! In the meantime please take antibiotics and cold/ice compress on it for temporary relief.

Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.

Wishing you good health.
