Hello. The most inexpensive/best use of resources to evaluate this is to have an ultrasound of the region. An ultrasound can tell you if they are just fatty tissue. And if needed a biopsy can be taken of certain masses/lesions under ultrasound guidance. The next level of testing would be a CT or MRI of the leg. MRI would show the soft tissues the best. I would suggest and ultrasound first if there is any concern. They most likely would be lipomas or small lymph nodes, however non-benign masses can't be excluded without imaging. Does that answer your question to satisfaction?
No urgent need to go to the hospital but I would inquire with your doctor about getting an ultrasound to confirm they are lipomas
that would be determined with the ultrasound. But no i don't suspect that would be a blood clot. Blood clots are deeper within the calf. Superficial veins can clot off at time but they are no issue
They generally arent painful, however if pressed on repeatedly and if superficial on top of the bone you may induce some tenderness. I'd still inquire about an ultrasound for confidence
Have a good weekend and glad to help
