Thank you for posting your query.
It is possible that the lump is pressing on the sciatic nerve
and causing your symptoms (pain in thigh, radiating to the left leg). This lump could be a benign tumor
examination and evaluation by a doctor would help identify the exact cause.
Please get back if you require any additional information.
