Lump in thigh 5cmx2cmx ?deep. pain when walking but not on palpitation. doc arranging ultrasound. is it lipoma or more serious?

See a surgeon: Usually lipomas are fairly superficial, painless, and relatively soft. If the mass is deeper and firmer, this can be a muscle or bone tumor, some are benign and some are not. If this is the case, you may need a ct or MRI to get a better idea of it's relationship to other structures. If there is a concern this is sarcoma, you should see a surgical oncologist, as the correct removal is critical.

Ultrasound results: Okay to wait for your ultrasound results. The most common diagnosis will be a lipoma. However that diagnosis is confirmed at the pathology exam of the lump removed at surgery. Once your doc has the us, a surgery referral may be the next step. There are some more ominous diagnosis, so make sure you get back to your doc.
