tweetyfeety

I've had 35 years at a job where I keep aggravating my already bad back(heavy lifting). If I'm careful I can manage, but after many painful episodes (usually a few a yr where I'm incapacitated), I now am having a lot of tingling in my legs & feet. It used to be only if I sat down for an extended amount of time; the past several weeks the tingling is present much of the day. I'm on a monthly maintenance program at Physical Therapy. I'm doing the stretches daily, but feel no long-term relief and am feeling really desperate. I feel so much better after PT, but as soon as I'm not moving , I stiffen up so much! I'm 54 and move worse than some people I know who are in their 80s. When I had to deal with a worker's comp Dr about 5 years ago, he pretty much dismissed me with a DDD diagnosis after reading my MRI. I don't know in he was just trying to protect the employer from any liability, or if the MRI truely didn't amount to much, as I doon't understand it. I'm now getting worried that the nerve tingling will end as permanent damage;any help would be appreciated. Thanks!
