How do I get rid of this ?

There really isn't a cure for Hemophilia. To keep from worsening the problem you should avoid aspirin, ibuprofen, or any other anti-inflammatory agents. Drink plenty of water and try replacement therapy. When you're bleeding externally, apply pressure to location of bleeding. When you're bleeding internal apply ice or put on a splint. You may also want to ask your doctor to prescribe you DDAVP (Octostim), Aminocaproic acid (Amicar) or tranexamic acid (Cyklokapron). If things get to bad you may have to receive an IV fusion.
