Relieve back pain symptoms and conditions

Was reluctant to take any Lipitor but decided to try it.
Now at 16th day of 10 mg tid.
Three days of foot swelling and eye and face swelling already. No other detectable reason of diet change.
Also severe low back muscle pains. No reason such as overworking it. The pain does not respond to movements which usually relieve back pain. (Pilates or Feldenkrais).
No proof of the cause but will stop the drug and test whether symptoms abate.
