My DVT's developed after back surgery. I have permanent nerve damage in my back. I awoke from surgery and had no feeling in my left leg and was finally discharged from the hospital using a walker. I had a home physical therepist come for about a month to help me out. I have total use of my leg now, but I have little to no feeling in my left foot. My DVT's developed from partial paralysis. I was on blood thinners for 6 months at 9 mg a day. The doctors just took me off the thinner one afternoon without checking to see if the clots were gone. I have since had another doppler done, however there is permmanent damage to the viens and they tell me that I will have swelling and pain for the rest of my life. My husband and I travel at least once a month by plane and the flying only seems to make it worse.
