I had blood clots that started in my legs. Thought I pulled a muscle at first but I hadn't even done shyt major and it wasn't even my leg workout day. Either way time went past, my shyt was swollen and hard, I just said fukk it and let it heal on its own.
Either way fast forward a few days later my leg appeared to get a little better but I started getting light headed and dizzy regularly plus I'd get out of breathe just going up a flight of stairs and a nikkas in tip top shape and healthy. My chest started to hurt really bad to the point where I couldn't sleep at night or breath normally and people keep telling me it was probably a broken rib or some shyt
I almost passed out at the gym, said fukk it and went to the emergency room. At that point I could barely breathe and was in the worst pain I ever felt in my life, no lie I could only breathe like eddy Murphy joked about in the safe scene in Harlem nights. Every breath had me fukked up because the pain
Either way come to find out I had blood clots the size of plums in my lungs and doctors told me I almost died, the shyt ruptured the lining of my lungs severely. They couldn't find out where they came from since all the tests came back very good and they were like breh you're healthy as hell, we can't figure the shyt out. I sat in the intensive cardiac unit for over a week getting visited by specialists around the clock, they had me taking morphine and vicadans every other hour. Eventually they got my blood thinned enough to release me but I'm supposed to be on blood thinners the rest of my life. I don't take that bullshyt tho, it is what it is but that ended up being a good thing
Long story short: I had a similar situation and it's easy to brush it off as a muscle strain or something minor because you can't really tell like that until it's too late. Hope the best for breh and he'll be able to come back but he'll be on Coumadins forever now
