I was monitored by a therapist. She started me with no weights--just leg lifting and then we went to using two lbs, then three--the four lb weights were probably the tipping point. I also had muscle wasting in my glutes as a result of my neuropathy--which may be due to my celiac disease. At another PT place, they went gungho and wanted me to do thirty reps of each exercise. If I said it was too much, then they told me that I was weak and would only face further degeneration. Be wary of PT--its not all its made out to be. Today I took a long walk around my local reservoir--had some pain but saw some honking geese and the resident swan. I told myself if I had arthritic feet, I would not have been able to walk this far. I had the MRI done but the doctor who is going to give me acupuncture says my problems were caused by the muscle wasting. I am not giving up!!!
