Hi!
I wrote the message regarding my husband. I am writing from Europe, Belgium so sorry for the mistakes.
I thank you for the information you gave me.
My husband has no problems urinating, only a pain to the prostate.
Now, with 600mg a day, he has nearly no more pain to the prostate but he has these pain to neck and lower back, I don't know if it is a "kidney pain"...
I didn't understand what you meant by "permanent damage to the kidneys"?
Does Neurontin damage the kidneys?
Good luck for the future.
