<s>[INST] I have a lump in th e top of my left foot. When I sit for awhile and get up to walk it is difficult for a bit but seems to loosen up. I work on my feet 8 hrs a night by the end of the night my shoes even bother the top of my foot. The lump seems to be getting bigger [/INST] Hi,Dear,Good evening.Thanks for the query to my HCM Clinic.I studied your query indepth.I am concerned about the worries you have.In my opinion,you have mostly-Ganglion ? or a bursitis.I would advise you to consult a ER-Ortho- Surgeon who would do-EXCISION BIOPSY if need be.It could regress after Antibiotics, Tb NSAIDs, Treatment for  5 days time.If it still grows and worries Surgical Excison is the treatment and would be done from ER Ortho-Surgeon.This would fix your lump worry.Hope with this you would be relieved of your worrysome query.Wellcome again to HCM.Have a good Day. </s>
