You would do better starting a new thread as this one is very old, Jen hasn’t posted on the forum since 2014.
If you are in that much pain, there’s no reason not to go to A&E, although they might not be able to do much.
Have you tried to get some guidance from your MS nurse about this recent pain? Have you spoken to your GP surgery to see if you can get any help from them?
Do you still have a stoma? Is the pain related to that, or the ‘hug’, or something else entirely? Or do you not really know?
And do you have any drugs that might help? Depending on what’s causing the pain of course. If it’s internal rather than nerve pain, perhaps the hospital might be a good thing. But if it’s the ‘hug’ or other nerve pain, then it might respond to a neuropathic pain drug.
