Leg foot cramps symptoms and conditions

I have been using Allegra for over 2 years. It worked for my allergy symptoms. There are side effects I experienced but didn't really make the connection until I started reading everybody else's experiences. I had headaches, ear aches and ear infections that wouldn't go away, leg cramps at night a foot cramps while driving. I was on several antibiotics for the ear infections. Severe headaches/brain fog at doses of 180. I tried an experiment by stopping the Allegra. Sure enough my ears have cleared up and no more leg & foot cramps. The down side is that my allergies are worse and I have been taking the old antihistamines Chlor-Trimeton & Benadryl.

Been on Zocor for two years went from 20mg to 40mg and since being on the 40mg I have increased leg & foot cramps so severe @ night that I have trouble getting out of bed, the foot locks up. Even getting up after sitting is a problem, sometimes my feet and legs go numb and I even fell a few times. I get very tired during mid day. The newest problem is my sight, I have notice that there is a blurriness that I don't know if it ever clear up, after telling my doctor this she said it was the arthritis and to take arthritis nonasprin and to stop the zocor for about a week, I am going to stop period.
