mom has all three arthritis's (severly) and has basically become wheel chair bound, however she has macular degeneration and retinitis pigmetosa (RP) where she is losing eye site. Her arthritis dr put her on Lyrica on 3-13-13, her vision has become more blurry, has the shakes real bad, little confusion. my question is: should we wein her off this since she already has bad eyes with her eye diease?
