Thanks for the welcome and for the advice/information. I have done the pill boxes - but I even forget about those and but I might look into the alarmed ones (all depends on price). The reason I don't think it's a strain is cuz it happened the first time when all I was doing was walking, and the other timew I don't do anything more strenuous than that either. I do lift heavy things at times and stretch at times - but that's not when this comes on. I will look in those forums, thanks
