Hi, I have recently had keyhole surgery to remove my appendix. Although it has been about a month now. However, I am usually an extremely active person, and have gone from exercising 2 hours a day to doing nothing (as I am in my final 2 weeks of University so spending every hour I have in the library). I am experiencing a really odd pulsating sensation in my right leg, on the inside of the knee. It pulses randomly, along with my hearts pulse, and it really jerks me and shocks me every time it does it. Any idea what this may be? Thanks.
