This is really getting me down, when i walk, every time i put my right foot down my calf feels so tight and sore and crampy, and i mean EVERY time. It has really violent twitches that really show no sign of going away at all.I have had this 6 months now and thought that this would be long enough not to be worried about ALS but booboo read that actually the onset is 5-10 months ! so still right in the middle of this.So does anyone have this constant pain???
