I've had chronic nerve pain for 30 years. Doctors have tried everything from Gabapentin to Lyrica. The last 10 years I've enlisted the help of a Pain Management clinic. The Pain Clinic has been pumping opioid into me for the last 9 years. My pain is so distressing I cannot function. The pain is in both legs behind the knees. The pain starts off slowly and is at its worse within a few minutes. The pain feels like someone is grabbing you from behind the knee and squeezing as hard as they can. Over the years I found that coffee has helped. I then switched to caffeine capsule upon the advice of my cardiologist. When I inform my doctors how caffeinne helps with my pain they either don't believe it or just pass it off. When the pain just starts off I reach for caffeinne before I go for the pain killers. Just recently I purchased pure liquid caffeinne to mix with water. I figured the caffeinne will enter my bloodstream much quicker than a tablet resolving in my stomach. I'm hoping to get off the opioid permanently. I was certainly surprised when I saw this article posted. I thought I was the only one suffering from this condition.
