Just to give you a little background. I have chondromalacia in both my knees from an injury when I was in an auto accident while I was on active duty. I shared the records with my ortho doc and he said more than likely than not that the calcification in my knees were caused by the auto accident and the resulting 5 years that I spent on active duty and 10 years in the reserves made them worse. I have been diagnosed with patella pain syndrome in both knees. In addition, I sprained my ankle while deployed for Operation Northern Watch in 2000 and now I have arthritis in my right ankle and it hurts worse than my knees some days. My ankle ortho doc also said that the arthritis in the ankle more likely than not was caused by the sprain. I still get shin splints in that ankle. I also claimed epistatis (nose bleeds), I was having real bad nose bleeds when I was in "A" school in the Navy, I mean like twice a day for two weeks. I still have a nose bleed today like once or twice a week.
