I was walking home from class yesterday and I got a very sharp pain in the skin of my right thigh. It is a very small area, but the pain hurts immensely. I looked at my leg, but there is no redness, burning, or swelling or any sign of a problem. It feels a little like my clothes are sticking to a pore of my skin and then pulling my skin off or sort of like an ingrown hair. It almost feels like a very, very small needle is stabbing me or like I am being bitten by something. It doesn't hurt when I don't move my leg. The pain becomes bearable enough to walk if I apply direct pressure to the point where it hurts. I have had similar sensations occasionally for my whole life on different parts of my body (buttocks, back, thigh, upper arm, upper leg) but none have ever been this painful or long lasting. I am a 21 year old male with good overall health. If anyone knows anything please help me! This is nigh unbearable.
