Hey Im sorry I sold the chair to a paraplegic guy 2 months ago. Im not doing bad by Quad standards, I havent had a uti in like 3 years, no pressure sores on my butt yet, bowell routines are going pretty good........my big complaint is the new pain I started having when the syrinx was found. It affects me in the mid back and stomach area, burning, cramping, feeling like someone is shoving something in my mid back. I continue to swim and lift twice a week regardless but it hasnt been easy. Im getting by with the 2 lorezapams a day and some amytriptyline at night. I did have some cool happen the first three months of this year. I met a girl from south america at the mall, and had an unbelievable time with her for three months. Well its over now but I will never forget it, Lol as far as your arm pain, I would see Dr. Wice and explain to him the pain your going through, that it is new and its scaring you because you already know you have a spinal syrinx, He may tell you to wait on the mri and say its not the syrinx, but I would tell him you would live and feel better knowing if the syrinx has changed and the only way to do that is with an mri. If you can rule out syrinx growth than you can investigate other avenues. You or me might get to the point where we have to get the syrinx operated on. Ill keep my wheels crossed for ya !!!!
