Since about one and a half years I'ven been having the following symptoms:
Tingling in left hand (up to the elbow).
Pressure on breastbone (where the ribs are attached).
Sometimes aching and numbness in my left leg. This feeling runs from my lower back to my calf where the aching is the severest.

I was wondering if this could have anything to do with an inflammation of nerves. And if so, what can be done about it?
My doctor prescribed vitamine B for the tingling in my arm, but that didn't really help. I have done PT, which helps a little but not for long.

Thanks in advance
