I was diagnosed with UC 4 years ago and after many flares, and many ups and downs, prednisone, etc. etc. etc., I am doing well now due to Lialda, and Dr. Swanson's Ultimate Formula Probiotics. This combination has done wonders for me. I was on prednisone for 3 years, started with a high dose which did ease the UC, but a taper started it all over again. As I said, many ups and downs. I always have a flare in the spring, and this year was no exception. Also, some have flare in the fall. Sounds like you had a fall flare and it never completely left you. Sorry about that. There is, no cure, but UC can be controlled with the right meds.
If you are at all interested in the probiotics I use, they can be purchased on line at swansonsvitamins.com. They have a three for one sale right now. As I said, the combo of Lialda (which is mesalamine & it's quite expensive) and the probiotics have made me quite comfortable. I'm not afraid to leave the house anymore, for fear of having an accident. Since I've been on these two meds, I do not have the urgency that was so awful.
Sometimes it takes more time to find the right combination of meds, but it can be done. Hopefully you will be successful and will find the answer to improve your UC. Diet is also important and that is a hit and/or miss thing. You are the only one who can tell what does and doesn't bother you. Keep track of different foods that you do tolerate well.
Keep us posted on how you are doing. If you have a good pharmaceutical insurance plan, perhaps Lialda would be the answer for you. When my gastro doctor prescribed it for me, he did give me some samples at first to see if they would help. He didn't want me to fill the prescription and find out they weren't doing the trick. Unfortunately, a lot of doctors do not get many samples anymore.
Good luck.
