Hi,Dear,
Thanks for the query to HCM.I studied your problem in depth and I understood your concerns.
Treatment for Painless lump on the leg-
In my opinion you seem to have-Pre-Patellar Bursitis(post-traumatic)or -which is developed mostly after the trauma you had few yrs ago.
So don't worry for the
Sarcoma,as by no means its Sarcoma.
Still if worried I would advise-USG and FNAC from ER Ortho- Surgeon, which would resolve all your worry.
For Final Diagnosis and treatment needs clinical data from a Doctor.
and Hence for further treatment I would advise you to Consult ER Ortho-Surgeon , who would treat it accordingly.
This advise is based on the facts from the history you give and needs further clinical check.
Hence I would advise you to check with ER Ortho-Surgeon.
So dont build up wrong concepts and create more psychic complications in you which would increase risks and costs to you.
Hope this would relieve your problem.
Welcome for any more query in this regard to HCM.
Write good resume and Click thanks if you feel satisfied with my advise.
Have a Good Day.
Dr.Savaskar M.N.
