Hard red lump

I have had a hard red lump on my leg for about 2 yrs now.  It doesn't get bigger or smaller, it doesn't hurt either.  Also, it doesn't move under the skin or anything.  It appears to be a spider bite or something but its been there for almost 2 years.  There is no white head, etc.  Its about the size of a pencil eraser or just a bit bigger.  Should this be looked at by a professional?

Hello,
From the symptoms it can be a small cyst. A cyst is a closed sac occurring just under the skin. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.

Generally no treatment is required but they become painful then it means they are infected,Then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required.

I hope it helps. Take care and regards.
