Head and neck pain symptoms and conditions

I've been on 80mg of Simvastatin for probably about a year. I'm a 59 yo male 188 lbs in good health but with high cholesterol. Lately I've experienced severe head and neck pain, shoulder pain, hand and joint pain, and foot pain. I'm normally very active, hike and walk a lot but lately, and it's getting worse, so I don't feel like doing anything. I'm thinking it's the Simvastatin causing all these problems. I don't feel like paying $1000s to have med professionals hit or miss with ideas and more tests so I'm going to quit the statin on my own and see if I feel better. I've also noticed memory loss, tiredness, dizziness, temporary vision issues at times. These are not good as I like to rock climb and participate in stressful and demanding activities.

I am a 43 year old female who, until I found this site, thought I was dying of bone cancer - I am not even kidding. I just finished the last of my 10 day prescription for Avelox (for bronchitis and sinusitis). And I feel like I have been beaten about the head and body. Honestly, every part of my body aches and I can barely walk. I have absolutely no energy; throbbing and shooting pains up and down my arms and legs. Not to mention sharp pains in my chest area periodically. I have very clouded and unclear thinking abilities; and my neck and head hurt so bad not even an 800 mg ibuprofen helps. Oh and let's not forget the chills which are right down to the bone - I cannot get warm and I have yucky night sweats to boot. I would most certainly be interested in a class action lawsuit. I really hate that I took 10 days worth and wonder when I will start feeling better. PLEASE DO NOT TAKE AVELOX - it is not worth the painful side effects! The prescription flyer I received with the medication did not mention any of the side effects I encountered.
