My Father was just laying down and had some bad cramps near his inner right thigh then another cramp not long after the previous cramp started on the opposite side then they went down to the top of his feet and around the front and backsides of his knees? If anyone has any input on this id appreciate it, I know a blood clot in between his heart and the arteries going down to his legs can cause a lot of pain but im not sure if they would feel like cramps but other then that ive heard marijuana being a great muscle relaxer has anyone heard or tryed smoking marijuana to relieve cramp attacks?
