Yes, it is often a balance of what is worse, the pain, the side effects or fatigue. Or sometimes all three.
I was given Lyrica by the pain clinic. Really, I needed my knees replaced by that point, but they said I was too young......absolute rubbish as my knees were trashed and fortunately replacement knees meant I could reduce pain medication. I also got hassle from my GP as I was on strong pain killers.......you cannot win. I hope the tablets work for you, I was lucky that there were other alternatives.
