It has been 11 weeks now after my surgery, and i still have a pea sized lump, and hardening of the vein above the lump. Is it serious ? i have revised my doctor twice about the lump, the first time was after two weeks from the surgery, and all they said is to put heat compression. I have done it a few times, but the lump is still there. Also the hardened vein and lump hurts if touched.
