Lipitor and post nasal drip

I was initially prescribed 20 mg of Lipitor as my cholesterol was well over 300 (365). However, the same week I started the 20 mg, I was hit my a car as a pedestrian and had so many aches and pains from that, that I felt the 20 mg of Lipitor was aggravating my recovery from the car incident so requested of my Doctor to "start" at 10 mg instead. I am also "medication sensitive". I have only been on the med for 4 1/2 months and initially things were "OK"...I did notice some aching muscles and joints, but this actually seemed to subside. However, in the past 4-6 weeks, many symptoms seemed to get worse...I feared I had Lyme Disease again, but the symptoms felt "different" though similar...aching muscles and joints...especially both my hands and wrists, hips and knees, very bad headaches, constant nasal problems including horrendous post-nasal drip and "face pain" like sinusitus, a feeling like I was getting bronchitis all the time and needing to use my asthma inhaler, even though my asthma is very, very mild, and profound fatigue. I also noticed "some" mental confusion and forgetfulness. I decided to go off the medication just two days ago and already feel better. I plan to get my cholesterol checked within the next week, but doubt seriously that I will go back on this drug...UNLESS it would be something like 5 mg every other day. I also lost weight (on purpose), have tried to get more exercise, and eat better as part of the overall plan to better manage my cholesterol...so, unless this continued health plan does not keep my cholesterol down, I will not take more than that of this drug (5 mg QOD).
