Hello,
Man it's been a long time since I've posted on here... brief history: I had a TTO and a bunch of other stuff in Sept 2003 on my right knee. I'm walking fine and was exercising regularly, but haven't been for the past 5 months due to a strenous work & school schedule.

Beginning yesterday, whenever I take a step (or put pressure on the calf of my right leg), I feel a weird pins & needles sensation in the back of my calf. It's not present all the time, and only intermittently when I'm walking or push on the back of my leg while standing. There is no pain or discolouration or difference in touch otherwise, but the leg (esp. knee area) is always cold. I'm worried that my circulation may be impaired & was wondering if anyone had any input. I'll be making an appointment with my GP to get this checked out as this is kinda freaking me out.
Thanks,
Marie
