My husband is having pain in leg since about 3 years. He feels pain only on pressing. Last week he went for ultrasound and his dr said there is some lump. He used the word Sarcoma and referred him for MRI scan. I tried to google the term and it freaked me out. We are so much worried. There is no swelling and no lump feeling on touching. Could this be something serious? He’s never been sick etc. Its just the pain.
