I have had 2 lumbar fusions within 3 months. The groin, leg, theigh,foot pain was so unbearable that they put me on lyrica for the nerve pain. It has worked. I am currently on 100mg. three times a day. The med starts wearing off 6-7 hours. I also take percocets every 5-7 hours for backup. Has anyone taken the meds like every 5-6 hours apart or does mg need to be raised. I read where the norm in like 2-3x a day. But for me, it wears off kinds fast. My short term memory is extremely terrible. Anyone else relate to this post? Thanks.
