Can t remember an exact date, but within the past 10 days to two weeks, I ve noticed issues with my gait in my left leg. This is a leg on which I had a TKR in July, 2007. Dorsiflexion is weak. And I cannot really stand on my left heel nor really walk just on my heels. Treatment so far is via my chiropractor as the issues came with lower left back pain/left gluteal pain. We are trying to see if something may be keeping a nerve from firing. Did some electric stim treatment today and will tray some massaging to see if the cause could be muscular. Another friend suggested I see a physiatrist. On my own I am using weights to try to strengthen my dorsiflexion. It was in spending time today online that I learned about the heel and was amazed that leaning on my kitchen counter to balance, I was unable to stand on my left heel. I am 64 and will turn 65 on 4-17-2015. With my current medical coverage having a $6k deductible, I am hoping to wait it out until Medicare kicks in. Your thoughts?
