Urine Retention

I started on MSM several months ago hoping to alleviate a trigger finger and thumb condition. I took it in the morning along with fruit and high quality Kefir that I make myself.
After some two months the trigger problem finger diminished, however one day after an increased dose of the msm I developed an inability to urinate. I stopped the MSM and Kefir and the dysuria condition abated. When I resumed the MSM and Kefir it came back. I've done this three times so I believe I have established the connection.
Now that I've been off the MSM a few weeks the trigger finger has shown up again. Please share your thoughts with me. William

One time I couldn't go and had to drive to town to get some cranberry juice.... One cup and my urine was back to normal. Now I keep cranberry tabs and extra bottles of juice in the pantry, save an expensive trip to town during the night.... Love, Joy
Weight Gain, Fatigue, Emotional

I used MSM for several weeks. Though I was very pleased with having thicker, more lustrous hair, stronger nails, No arthritis pain and increased energy, I couldn't help but notice that I gained 14 pounds!! After continued use, I became an emotional mess, along with fatigue as opposed to energy. I stopped for a week and the weight is dropping. I want the beautiful, skin, hair and nails to continue. Is there a comparable supplement?
