I e-mailed them a couple of weeks ago and I am still waiting for a reply. Right now it is a very consertive (sp) treatment, he has a compression sock he wears during the day. I have noticed that when he dosen't wear it, like on the weekends (he plays outside barefoot) his foot will have a sight purple tint to it and he says that it hurts really bad. I have tried just wapping his leg with a ace bandage but then his foot will really turn purple. He told me after he got his sock that he didn't realize how bad his leg really felt because he was just so used to it. Anyway, I just really want/need more info I feel like I am walking around in the dark.
