I will try and describe this the best I can. I am having to rely alot now on using a crutch. The further I walk the more difficult I find it becomes. Its my left leg. The calf starts to hurt and above and around my knee. I become a bit breathless to. My leg feels tight especially at the back of my leg. Then I feel dizzy and quite light headed. So I use my crutch basically to keep me steady. My walking becomes a chore as I am usually worn out and left with a leg that throbs. The throbbing extends to my foot eventually. Does anyone else get this. Its becoming harder and harder.
