I am a 44 yr old female with a history of gastroparesis, gerd, metabolic syndrome and pcps...i have had a pulsating on right side (inside) of left knee all day on and off..can see it pulse..doesn t hurt doesn t pulse with the pulse in my neck...doesn t feel like muscle twitching..seems to go away when i move...more noticeable when i am sitting standing or lying down..
In my opinion you have a popliteal aneurysm I recommend you do a dollar to be safe Please take it seriously Good Luck
