Did you have bladder problems prior to started LDN?
Yes, definitely, but these problems were aggravated by LDN. Same with night time spasticity in the lower legs. I've finally stopped using LDN entirely because of these problems.
Retention is still a problem. but I get-by using manual pressure to empty my bladder, and I still have the occasional accident if I can't make it to the john in time. But, while using LDN I had to self-cath several times a week, and I had constant bladder leakage (bi-weekly ear-acupuncture helped mitigate this for me, but I'd rather not deal with it at all). This went on for an entire year without lessening. I thought it was solely due to MS, and didn't realize that LDN was aggravating this problem.
I stopped using LDN in advance of the 2009 CCSVI stent procedure, and assumed the sudden lessening of spasticity was due to the IJV correction. With hindsight, I think this was primarily due to stopping LDN.
I've tried reducing the dose to as low as 1.0mg nightly, and it doesn't help enough for me to continue using it. I've had nights that required 12+ trips to the head, but without LDN, I typically get up about 3 times. The LDN benefit WAS NOT worth the side-effects, and the side-effects DID NOT lessen with time, thank you very much.
