I to suffer from IC. For relief they can give you a dye pill that numbs your bladder. It's called Pyridium. Generic is Phenazopyridine. It's normally 200 mg and is a tablet. It works for the most part. I use it daily and with IC surgery is sometimes recommended to break the nerves so stop spasms and pain. The condition cannot be cured. Surgery will normally be needed.

Cut out spicy foods from your diet completely. AZO worked well for me during flares but if I didn’t have any I’d use a heating pad over the bladder and drink lots of water. I’ve tried marshmallow root, d-mannose, CBD, probiotics, everything under the sun. Now I have trospium which may work for you. Ive found that my diet is a huge part of my bladder pain

I take aloe very capsules that help and I take cystex every day both help. Also I have been on elmeron for a few years

I’m same as you, did anything help the urgency and frequency ??
