Brenda,
Welcome to the forum.
Glad you found us, although I wish it had been under better circumstances.
I am so sorry about how much pain (physical and emotional) you are experiencing.
UC is a tough disease, both physically and emotionally, and can take its toll.
Like the others, I am very concerned at the level of pain you are now experiencing, along with how little you weight.
As pro-natural remedies as I am, I don't think this is the time to take that leap for you IMO.
You need to be seen by the ER or Gastro sooner than later, very soon - because it sounds to me like the levels of pain, cramping, symptoms you are having might be indicative of a much more serious situation than just a flare, and I am very concerned that you might not be getting the care you badly need.
IMO, Once you get put on the proper meds, whatever they might be, so that your levels of pain, cramping, and symptoms are fully diagnosed and handled, then you can take the steps to explore other natural protocols, diets, supplements - and even start them once you are at a more stable point.
I feel for you, and hope that you get some good gastro care to get you into a better place.
Let us know how we can help. Know that you are not alone in this. We are here for you.
Sending you a big hug.
