I have been experiencing odd but normal things recently, and was just wondering if I should be worried. I have been suffering with what I assume to be allergies for almost a month now. Weird things have been happening, like my eye twitched about 20 times a day for a week, and suddenly today my right foot keeps getting a sensation of heat. Not painfull or anything, just warmer than body heat could be, kinda like a heat pad or icy hot was put on right under the arc of my foot. I don't want to seem stupid, but what could cause these trivial symptoms?
