About 2 weeks ago, I started having pain behind my left knee. I called my docs office and they told me to increase the neurotin. So now I'm taking 900 mg. total. Well, the knee is still hurting. Talked to my doc's office and they are sending me for an MRI on my knee. Since I have a $5,000 deductible, that will have to come out of my pocket (new insurance eff. 9/1), I'm worried that this will be a waste of money. Am I making any sense at all?
