I am not sure my symptoms are related to Lipitor, but it is the only med i was taking and when i finally suspected the connection 3 wk ago, i stopped taking it.
It occured to me that i was complaining of muscle and joint weakness in conversations with others, but related it to my age (53) and lack of exercise. Then i had a few episodes of sudden brief cramping in my back muscles -- totally unexplained by anything else -- and a couple episodes of dizziness, or true vertigo, while sitting and typing at my computer (i am a medical transcriptionist). Those got my attention. Come to find out my mother and brother also had identical muscle problems and switched their cholesterol medications away from Lipitor.
There are numerous other little things, running into walls and furniture, numbness in my feet or hands, yes, the cognitive things i've read here too, etc. Again, don't know if it is the medication, but after doing some reading of other's experiences, i do plan to do my best to improve my health withOUT the use of medication.
