Ihave been taking 20 mg Lipitor for 3 years and have noticed loss of feeling in the ends of my toes. This loss is now extending to all my toes and my ankles are getting stiff. I have trouble standing if I have squatted down and from time to time have difficulty swallowing. Some times , particularly when out in the wind, I have great difficulty breathing and now carry an asthma spray. Is all this due to Lipitor.??? By the way I sometimes hit the wall when walking and have to be careful going down stairs. I also suffer from gas and constipation.(61 years, female, tennis player)
