What causes sharp twinges near pelvic bone?
Patient: Hello, I seem to have a sharp twinges (not really painful) on left side between top of thigh and pelvic bone. It feels like it is right in the artery or vessel - whatever it is that is there. It kind of pulsates when I touch the artery. It is not painful but a twinge sensation. I do a lot of running and I am 65 years old.Don t feel like it is anything but muscular but not sure.Any ideas? Doctor: It might be a piriformis muscle spasm which caused twinges.or might be some vascular prb I am not so sure bcs need to be examined.  But if you feel it is muscular prb you search for periformiss muscle streatching and do stretching.apply hot pack.
