I'm soon coming up to the age where I can legally serve in the British Armed Forces, but...I have a once serious, and now mild, medical problem. I suffer(ed) from something called Perthes disease caused by osteonecrosis of the hip. This caused my hip ball joint to deteriate and fragement around the edges. Luckily this happened when I was about 4 or 5 and was treated quickly. My current condition is classed as "Healed Perthes", but is still being monitored by a consultant. These days it has no real adverse effects. I get mild pain in it occasionally after a lot of physical activity, but this pain only comes in the night, or when I am resting, and quickly fades when I start to move the joint. I personally believe, although it limits the amount my hip can rotate (almost NOTHING in comparison to my healthy hip these days), I can pass training. The only thing I am worried about is that this condition causes me to be barred from the military. Also to add; If I found myself eligible to enter the regular forces, would it stop me moving up into the special forces? Assuming I could pass training, would this stop me? Cheers for any help on this, I want to be sure I'm doing the right thing.
