I've been noticing that my vision has become more and more blurry over the past few months. I also had been having trouble urinating with ease. (Basically, it would take a while for my bladder to decide it was ready to release its contents). I had read that Cymbalta(taking for pain) could cause urinary retention in some people. I let my rheumy know, so he lowered my dosage from 60 to 30mg. A bit later is when I began to notice my vision was worsening. Even with my glasses everything seemed blurry. Went to ophthalmologist and she told me about the systemic connection between the eye and urinary bladder. I was blown away! Who would think the focal refraction muscle and urinary bladder contraction would have the same nervous system stimulus? So she suggested I let my rheumy know, and tell him take me off of Cymbalta just to see if there would be a change in my vision, as well as my urination issue. (My vision had lowered 5 levels in seven months, by the way.)
Since being off Cymbalta, I have noticed that I am seeing a bit more clearly, and peeing definitely isnt a strain anymore. I will revisit the eye doc at the end of Dec for a recheck of my eyes. Hopefully, all is as well as I think it is. Body pain is not good though. I may try 20mg of Cymbalta to see if it helps pain without damaging vision and bladder functioning.
