Thank you Dr. Crane, for your good advice. I did go to my Dr. immediately and she confirmed my suspision. It was the 10 mg Norvasc. I had been taking a lower dosage for awhile with no reaction. When the dosage was raised to 10 mg I started with the swelling and cellulitis. We caught it early and it healed quickly. However, the heavy swelling in my legs lasted for several months, gradually reducing until it was gone. My Dr. had told me when she stopped the Norvasc that it would take quite a while fror the swelling to go away. It was interesting, when I knew I was on the mend, to see my skin stretched to the fullest and to have no ankles at all! I would advise anyone with quick and unusual swelling in the legs to see their Dr. right away.
