I have mild Osteoporosis. I went to Osteostrong for 6 months in 2021. I had also moved and was in an apartment while my house was being built with a very poor mattress. About 2 months into Osteostrong I started having severe tendon pain in my shoulders and hips. I attributed it to my mattress. I quit Osteostrong as I was just too busy moving into my house and didn’t have time., and it hurt too much. When I moved into my house I got a brand new Orthopedic mattress, thinking this may be what has given me such bad tendon pain. It has improved somewhat, but I am still in a lot of pain. I have been going to physical therapy for 5 weeks and it is not helping. So now I have scheduled an appointment with an Orthopedic Surgeon. I am going to discuss with him if doing such heavy load bearing at Osteostrong could have damaged my tendons. I cannot think of what else could have done this.
