Not enough strength work...Fellow old folk,
Lately, my right knee sometimes give the most almighty crack when walking, it's not painful, but not a nice feeling when it does it, and not nice for the person I'm walking past at the time
Anything I can take supplement/herb wise that can help with this? I know Freefaller will probably have a good recommendation
It's probably not very serious, but it could be that tightness/imbalance is pulling your knee slightly out of line. That could lead to bigger problems.
Supps/herbs can't do anything to fix that.
If you really want to address it, my physio works out of LA Fitness in Oxford and I could give you his number.
