For a while know I've had a strip down my right leg which is numb, on the left hand side, nearly all the way down to the ankle, I thought I may have done something to it without realising.

However with more recently developments, such as my right elbow going numb, (over 30 hours of numbness now)

Also, just before that my middle finger on my left hand has swollen at the tip, around 3 days with no improvement (I didn't hit it to my recollection, same goes for all the other incidents, to the best of knowledge I did nothing to cause it, this is I'm why worried.)

Any ideas would be greatly appreciated, I'd really rather not go to the doctors if necessary :x
