There's that advert on TV currently that shows a DVT moving along a vein towards the heart/brain in SMOKERS - creepy to watch.
About a year ago, I learned from my father in law that a colleague of his was sitting at home with some friends when he started to complain of a pain in his thigh which then moved to his abdomen, then his chest, his neck and minutes after he complained of this 'uncomfortable pain' he was dead from a stroke!!!!
All this was witnessed by about 6 people...... Creepy.
Aspirin has too many side effects.
Try lots and lots of H2O........and keep moving.
