Hi I am new to this board and have a couple questions. I am an active duty Marine. I have been in service for 7 yrs now. Just last year I had been diagnosed with a Pulmonary Arterial Venous Malformation( 2 of them). It ruptured and I almost did because of it. The fix was to put a coil on my lung between the vein and artery. Since we must maintain top pysical shape I am required to run alot. I constantly get chest pains when i do this. It scares me It might rupture again. I also cannot run like before. I am so out of breathe it isnt funny. I get out of breather just playing wit my little ones and doing normal activities. The Docs said I would loose some lung capacity. When I run I am gasping for air in no time flat I almost fail the USMC minumum run requirement. I in the past always had a 1st class score. I have 2 kids and a wife. I donot know howmuch longer I can keep this up to pay the bills. Do I have potential fo a claim with the VA? If so how much %? This is my second tour and would this qualify for Med retirement? Please help.
