1000s 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 was first prescribed Neurontin in November of 2008 for cervical disc bulge touching my spinal cord causing severe nerve pain in my left extremities. I was prescribed narcotics and eventually prescribed Neurontin. The side effects from Neurontin, at that time, were seemingly intolerable, but as the narcotics were decreased several months later, I found the Neurontin was actually effective and did its purpose. The side effects from the Neurontin were not that great to outway the pain factor I had. I believe this drug does its job!!!!
