Does anyone have experience with this? The doctors here don't seem very well versed in Syrinxes or Syringomyelia. We are going tomorrow for additional MRI films to try to determine the cause and if there are any other problems. What are the possible symptoms that a syrinx at the T7 thru T11 level may cause. Could they be-- Headaches, occasional sensation of not being able to get enough air, severe back pain and falling simultaneously, legs feeling like jelly mostly after activity, random pains in the extremities, and more????????? Thank you.
