I have the sensation of a rubber band wrapped around the base of my big toe. I did have three musculoskeletal events happen to me last year. May 2015 a cystocele repair with rotor implants placed into my ligaments in pelvis/ hips, with a rectocele repair. Then while I was healing 4 weeks post op fell flat on my back. Then 3 months later jumped away from a rattlesnake and pulled my right hamstring where it connects into the Itial Tuberosity in my right leg. That last injury was so bad that in ams I would roll out of bed and fall on the floor crawling to the bathroom. I had alot of pain in my right hamstring. However I was able to work and go on a couple of camping/hiking trips. I hike and walk alot plus do Zumba and started to go to Physical Therapy for 14 months of low back pain. I had an MRI of my back and now I have mild degenerative changes in L4, L5, S1, and S2. I Have a weak core, and I am getting the PT for my low back including just starting core exercises.
