Hi,Welcome.
Based on the facts of your query,You need to check with your
dermatologist and Surgeon if need be,as you were on medicines since Feb.
As the lump is painful,and still not healed,I suspect-
Varicose Eczema with painful infected bumps,as you have 1/2 -3/4 th shin involved with it.
Treatment-
A
second opinion from Surgeon , would fix the cause of your lump. and would treat it accordingly along with your dermatologist team.
Hope this reply would answer you query and would help you to take care of it.
