Pregabalin
"This worked wonders for me but I have an allergy to it, was warmed it would make me drowsy but made me have crazy anxiety and tight-chest. Problem was it completely eliminated my sciatic and lower back pain. Couldn't cope with side effects on 75mg so dropped to 25mg, still too harsh side effects. Moved on to Gabapentin in last 48 hours which has seen back pain return but no sciatic pain or tightness. I am allergic/have a bad intolerance to caffeine and it was exactly the same reaction. Sadly due to side effects this tablet didn't work out for me"
