about six months ago, i started having numbness and tingling in my arms and legs. I also experience a great
deal of pain in my legs (especially in the part from the thigh to the knee). This pain usually comes after taking certain medications. However, there are times when my legs feel so weak I feel like they will collapse if I try to walk on them. I have recently started having constant chest pain too. I have been to doctor and had several tests done all of which came back normal. any ideas what this might be?
Thanks
