For the last six years I have been experiencing inner leg from stinging/tightness like a rubber band. At first I thought it was due to my varicose veins so I had that taken care of. But they still continued in one leg and now they are in both legs. I also had two knee replacements but this started before I had either of them done. It usually happens when I am on my feet for a long duration during the day. Sometimes I can prevent them by stretching them , but if it gets too bad, I can t move only stretch by putting my hands against the wall. The stinging/tightness starts on the inside of either leg from where the torso meets the leg to above the knee. It never goes below the knee. If I bend one of my legs I sometimes can feel the stinging/tightness starting. I do take 5mg or l0mg of cyclobenzaphr and it does help. I also have back issues , not seriously but feel this does come from the back. My question is what can I do to prevent these. Is magnesium a good source? I would appreciate any feedback on this. I am 68 years old and live in Wisconsin. Thank you. I have asked several people with b ack problems if they ever experienced this type of stoning/tightness in their inner leg but no one said they had. Thank you.
