<s>[INST] Hi Doc I have had numerous back operation -last one in 91 with titanium prosthesis, my problem is not my back as such but a complete numb foot and the numbness spread right up my right leg.  With it very bad (severe) pins and needles with ice water running down legs.  Now I have developed a kind of rash and it stings not so much itching. It is spread randomly all over body. I am 65 years old and have severe scoliosis.  My left hand cannot hold anything it shakes and then I drop whatever I pick up with forefinger and thumb.  My main problem is the totally numb foot and pins and needles with muscle spasms and eye twitching.  Thanks, Ivy [/INST] HI I AM YOUR DOCTOR WELL THE SYMPTOMS YOU DESCRIBE ARE DEFINETLY BECAUSE OF NERVE COMPRESSIONS THAT MAY BE EITHER BECAUSE OF SCOLIOSIS OR ANY OLD DISC BULGES AFFECTING YOUR SPINE. I SUGGEST YOU GET A FRESH MRI DONE TO EVALUATE THE SPINAL CANAL. BY THAT TIME YOU NEED TO START ON GOOD NEUROTONIC DRUGS LIKE PREGABLIN 75 MG OD AND TAB SERTRALINE ALSO HELPS IN CHRONIC PAIN . THANKS </s>
