Hello, so I have a metal bar with hold on with pressure in the middle of door walls and I do pulls ups on it every morning and it never fell down, but today it did fell down while I was pulling up and I landed on my feet with the metal bar in my hand and I felt a sudden pain in my slightly up of my middle back followed by a vomiting sensation for a moment and then it went away shortly. Now I feel a slight uncomfortable pain in that area. The pain does not increase when I move, bend, breathe or stretch it only increases if I jump. What do suggest for me to do?
