When I work out it starts to feel like im getting needles pushed into the back of my brain. its sharpe and quick continuous pain. My chest ( not as often as my head) starts to feel like someones sitting on it. I can still breathe okay through all of this. the more often I work out the long the needles in my brain lasts and the worse it gets. I have just recently started working out 4-5 times a week.
Hi, I am Chat Doctor.  I have read your question and understand your concerns. Let me try to help you have described signs of Ischemia When you exercise, too much blood is shunted out to the muscles so that the other parts gets less blood supply and hence you get the symptoms you have mentioned The solution would be to reduce the Weights / Counts of your exercise for few days and then gradually increase them This is easily manageable
