My mother, whom had been very active and healthy her entire life, discovered about a year ago that she was suffering from Afib and congestive heart failure. She began taking Renexa and Coumadin, and almost Immediately had difficulty walking and fell a lot. She now walks with a walker and still has difficulty because her legs are palsied and weak, the doctors diagnosed it as spinal stenosis. I dont agree with this diagnosis because she was diagnosed with spinal stenosis several yeRss ago and didn't have any problems walking. Once in awhile her hip hurt and she would lie on a heating pad for relief. The failure to walk and the palsy occurred simultaneously with being medicated.
