Two and a half years ago I was cut in the shin of my right leg with a knife that was pretty deep. Went to the hospital, got 11 stitches and healed up with no problems. Now suddenly I have this TERRIBLE pain in my left thigh that really really hurts! I'll be laying in bed or standing/walking around and I have to stop and pretty much fall to the ground when my leg starts hurting. It's a throbbing, burning, heavy stinging spot that hurts really bad. When the spot is touched it's really sensitive and I scream and wanna cry because its so painful. It throbs when i just lay or sit here and i dont know what it is and i dont have money to see a doctor. please, any suggestions. There's no bruise or redness of the skin.
