For the past couple of days I have had deep pain in my right knee and ankle. The pain in my knee is just below the knee and feels like a rubber band constricting my leg. The pain in my ankle is also deep pain as if an injury to a bone and the pain circles the ankle. In addition to that, there is a bulge in the Achilles tendon that was extremely painful a couple of months ago. I have been fairly active as a 51 year old female, however I have already had total knee replacement on my left knee and disc fusion, rods, screws and cages placed in my low back. (Yep, walking train wreck). Lastly, the muscles on the insides of my legs feel as if I ve been riding a horse for days. Is there anything that could account for all of those symptoms, assuming it isn t due to stress & over use? This doesn t feel like pulled or strained muscles and I haven t had any falls or other injuries.
