<s>[INST] I have a large white lump on my heel and it has made my heel numb and bruised and had a pink center on the top of it, it s making me limp very badly. It feels like a rock is in my skin and it s constantly burning. I ve been told this could be a Plantars wart but it keeps swelling and getting less bearable to deal with... What could this be and how do I get rid of it? [/INST] HiWelcome to hcmThis can be a corn which has got infected or something got pricked like thorn or glass piece which is developing into abscess. You need to remove the causative factor (thorn or glass piece) and drain the pus or remove corn if it is the cause. For this you have to show it to your surgeon. Also antibiotics like amoxacillin with clavulonic acid 625 mg three times a day for 5 days and tab chymoral fort three times a day for 5 days will help. Tab brufen can reduce your pain. But most importent is its surgery.Regards </s>
