I Suffer From Slipped Discs And Take 2100mg Gabapentin ,

I suffer from slipped discs and take 2100mg gabapentin , also codeine along with 10mg sevredol as required , I now suffer from swollen and painful hands and numbness at night . And to make matters worse I have a pain that affects both sides at the front of my stomach but only at night , it does not affect my bowels ! Not sure if I need to go back to bother my go ?
