I have been on Lyrica for nerve pain from mastectomy and chemotherapy damage - neuropathic pain.
It has helped and was the only thing that got me not to dread every slight move for all over body pain. It unfortunately has some side effects. Take it as directed. Do not forget doses. Make a small few days supple to store in you car or purse.
I find afternoon fatigue ongoing from taking Lyrica. But much better than the extreme pain. I find I still have break through pains and sharp nerve pain. But if I sleep week it's not as bad.
Im on 150 morning and 150 evening.
Also I find it best to take evening at 8pm. If I wait until I go to bed the pain has broken through.
Good luck. Most people's breast pain slowing disappears. My breast pain is mostly gone. Only occasionally nerve pain like I have a breast still.
