Possible DVT Issue - Need Help

[rob3306]

Need some advice/help with some possible DVT. My issue is right now that I can't exactly go see a doctor about my leg but after some research, it seems as if my injury is dvt. A little background - I'm in the military and went through a course about four months ago which badly messed up my IT band. I made a makeshift band for it which I placed right below my right knee cap during the course. It helped my knee pain but in turn caused some serious pain behind my knee. After the course, I rested for about a month and most of the pain went away. Over the past three months I have completed other courses with little to pain and these were pretty physically demanding courses. Now about three weeks ago, I was doing a difficult physical event for the military and after, behind my right knee started killing me. I could barely walk for a few days and I thought I just had possibly reinjured that area. Now three weeks later, behind my right knee is still hurting and I leave again in a week for another course. Does this sound like DVT? The only reason I think it is is because four months ago that makeshift band could have possibly dug into the back of my knee and caused some sort of clot. But it's weird it didn't hurt at all the past three months and then popped up again out of nowhere and this time was the worst. Any help is appreciated. Thanks.
