What are the general recommendations about exercise for people having problems with TCS? On several internet sites I have seen "warnings" about stretching & bending in particular and exercise in general for people with tethered spinal cord. Two weeks after beginning cardio rehab to improve my general conditioning, not because of heart problems, I began to have sudden & terrifying leg problems. At age 59, and already diagnosed with neurosarcoidosis, an MRI found TCS & benign tumor. My neuro does not seem to be familiar with TCS problems. I'd like to return to the cardio rehab prpobram, but I am afraid of more TCS problems.
