Hi, I have suddenly developed a pain in my left calf approx. 2 inches from my knee on the inner side. It began to feel like a charley horse, instant pain, cramping. Not nearly as bad as a Charlie horse, I sat down lifted up my pant leg and noticed a bruise developing, the bruising is sort of dissipating however it is still there. In that spot alone feeling like a cramp and somewhat hard at the touch. Like a lump under the skin. Should I be concerned? I have had veins bust in my leg before but this is different.
