Two days ago (Wednesday Nov. 26) my 5 year old son and I bonked heads - the back of his head to my right temple. Experienced immediate flash of white light. Experienced occasional shooting pain over to my right temple area over the next 24 hours and temple was bruised. This morning I woke up with tingling in all of my extremities (face, lips, fingers, hands, arms, legs and feet). Feeling a bit fuzzy and am a bit nauseous; also woke with mild diarrhea. Likely to be related or am I fighting some sort of unrelated infection? Thanks Kathy
