my nose suddently started bleeding just then, and it doesn t appear to be caused by blowing my nose too hard, because i have experiences in the past when i blow my nose too hard it bleeds but it s never alot, this time it is alot of blood....and what happened so far is that i have a cold and i took cold and flu tablet last night, and this morning for the first time i had protein shake for breakfast, because i want to loss weight for the coming up wedding as a bridesmaid...so i am just thinking to myself could it because of the protein shake? i am really freaked out because i tend to think the worst....q
