Thanks for sending your query to us.
I have seen the pics. From the description provided and pics attached, it looks like dermatofibroma. A dermatofibroma is a benign skin colored elevated lesions usually seen over limbs. It might be asymptomatic but sometimes presents with pain or tenderness as you have mentioned. Clinically it can be confirmed by dimple sign ie when lesion is pressed laterally,it almost disappears.
Usually the lesion can be left as such but if its too tender its better to get it surgically excised.
Hope this helped. Should there be any doubt, please write back. I would be happy to take the discussiob further
