I had problems with my right leg a while ago, kept giving way, felt like my knee was gong to pop out, but it cleared up, leaving just a general feeling of weakness, I can't rest my weight on it when standing, it just feels a bit absent! But today I have this really freaky thing going on. It feels like something is rubbing/brushing against my knee and just above and to the left, rubbing or gently squeezing, like a ripple. Its so weird and hard to describe, not painfull though. I'm of to the doc this afternoon, for something else entirely, should I mention it do you think? Ive got a scan coming up next week.
