Control blood pressure symptoms and conditions

I was on Lipitor for less than a week 2 years ago and the muscle pains were so bad that moving my head was painful. I called the doctor's office and was instructed to stop taking the medication; which I did and felt 'back to normal' within a few days. I haven't had my cholesterol checked since that time, or if I did before surgery, no one mentioned anything negative about it. However 6 weeks ago I had a heart attack. Apparently my cholesterol was twice what it should it have been, and my potassium was incredibly low. So I'm now on Lipitor (standard procedure after having a heart attack and high cholesterol seen as the cause of it) to ensure that another blockage does not occur.

The only problem is I'm now bloated even though I've changed my diet drastically (no more junk food or soft drinks, no 'white' flour products, no dairy products with more than 5% M.F and lots of veggies and fruits). I've lost 3 or 4 pounds but my pants are too tight around my waist, and now I have a my upper abdomen bulges over the waistline. Besides that, I get muscle 'kinks' in very places and after sitting for more than 10 minutes I limp when I take the first few steps.

People have told me to 'keep taking Lipitor and Plavix' but exercise more. The only problem with that is that I have a brain aneurysm and the neurosurgeons don't think it can be operated on 'without it being a very high risk procedure'. The first one ruptured 10 years ago and since then I've managed to control my blood pressure. However the meds I took for that was what lead to my potassium being so low that my electrolytes were imbalanced. That combination of low potassium and high cholesterol is what lead to the heart attack.

I'm 54 and feel as though I'm losing control of 'how' I feel. Between Lipitor, Plavix and diuretics and medication for hypertension I'm not sure if it's one drug in particular that's making me 'ache, limp and look like a blimp' or if it's because of the interaction of all of them. How do I decide 'what' to stop? What's more important to look after first - my heart or my brain?

Have developed knee pain and can no longer run since being on toprol for three months to control blood pressure. Have been running for 28 years and never had a twinge of pain until this.
