Dear sir, I recently injured myself playing kickball, I ended up pulling muscles and my right knee was swollen, since the injury (about a week ago) My Left leg has been numb, from the knee down. I have a few small scabs on my left foot from the sand, and I have a horrible habit of picking at them, but as I pick at them, I don't feel my nails digging in my foot. I was wondering what could be wrong or what I could do to help. I am 16 (female) 5'7 and I am somewhat overweight, Diabetes runs in my family, but I have had no symptoms as of yet. Any Advice is greatly appreciated, Thanks in Advance.
