Thank you - I am writing on behalf of my husband. He has lymphedema in both legs and has had a heel spur on his left leg (worse one) for about 2 months. He has had gel heel pads in both shoes (special shoes to fit his swollen ankles etc. and in the last week has had terrible pain going from the knee up the thigh on the right leg - so much he can only walk by holding on to the walls or with a stick and then very slowly. He is 79 years of age and has had quite a few health problems.
