What can be cause if lumps ?
Hello. I'm Dr. Phil, licensed and practicing internist. Excellent service is my goal.
can you explain the question more?
Customer: replied 3 years ago.

Well I have a small lump on my upper left arm which has been there for approx 3,4 months I've noticed and is painless

can you take a picture?
Customer: replied 3 years ago.

U can't actually see it u can only feel it

I see that the other expert has opted out. I am Dr ken and I would be happy to help you.
Is the lump soft or hard? Is there swelling or redness at overlying skin? is the lump growing in size? Were any investigations done to see for the cause?
Customer: replied 3 years ago.

It's hard no redness or pain

I assume it is not increasing in size as well.
Arm is a complex region of the body. There is underlying bone {humerus} with overlying muscles, vessels, nerves and fat. Abnormality at any of these can present with lumps. I would consider benign lesions in your case {not a cancer}. The ones arising from fat or muscle are more common and so they are more likely.
Next step - A physical evaluation along with few investigations like ultrasound {if needed} to get more answers.
Generally benign lesions do not need any treatment or surgery.
Wish you well.
