My right hand is numb along with my right foot. I was injuryed at work lifting in 2009. I had back surgery in 2010. I have had a lot of testing done. All of which is normal. But, I continue to decline and have many other health problem that goes along with this..... I know my body and something is wrong. Can u offer any suggestions? To guide me on the right path. I m a white female 34 years old. My height is 5 9 and weight is now 180. I have bladder problems, blurred vision, muscle spasms, balance issues. I used to have tremors but, they have stopped. My left leg shakes along with my right arm. I have constant dizziness, nausated. I also no longer fill hungry anymore. I eat small bits and get really full. I have high blood pressure which was 140/100. My right leg is swollen along with some swelling in right arm. I m in constant pain. And I ve been in 8 months of pt and they say their nothing more they can do for me....... Any thoughts would be helpful. Misty
