What does a hard bump on thigh indicate?
Patient: i have a bump on my left thigh, feels hard under the skin like I hit it... have a little bit of bruising. I'm 30, 5.6 ft, healthy, noticed it a few days after I did hot yoga, not sure what exactly its from. recently had a bay (3 months). had a blood test done - the hormone that should be in the blood if the muscle is torn wasnt found, had an ultrasound of the thigh tissue - normal. Doctor: HI,Dear, Thanks for the query from you for  your painless hard lump under the skin in lt. thigh.1-I feel concerned that you are serious to know where from this hard lt thigh lump- occured after the hot yoga or may have occured  when at the bay 3 mth back.?2-In my opinion this hard lump had a bruising meaning thereby it occured from a blunt trauma during hot yoga or trauma when at bay 3 mths back-which is the remote possiblity as its bruised , and most probably appears to be due to trauma during hot youga as it appeared after few days after you did hot yoga.3-In presence of the normal hormonal levels for the muscle injury, it appears to be hit 3 mths back -leading to hard -organising hematoma,which got bruised after few days of hot yoga.4-USG study / Muscle biopsy studie,would fix its origin and cause of development.I would advise to have surgeons opinion from your ER.3-I would advise FNAC to fix the reason ans hence would refer the case to ER Surgeon. 5-Hope this would solve your worry of the hard lump on the thigh.6-Wellcome to HCM for any more query.
