About 3 months ago I started with a dull ache in my right knee, followed by some shooting pains in my shin. Then almost a throbbing feeling in my thigh. I am 28 and this is becoming a bit worrying now. The pain has worn off from when it first started, but the aches still comes and goes, but it is now starting to ache in my left leg. I haven't injured myself, so I know it's nothing to do with that. Could there be an explanation?
Thank you
