Mesenteric Panniculitis

During Covid, I found myself in the ER twice in a great deal of stomach pain. The CT scan showed MP. The GI doctor refused to believe I had it because all my inflammation markers were normal. Fast forward, I continue to have flares and scans show MP.
Overall, I am in excellent health. I am going to add some supplements and tweaks to my diet. What can I expect as far as medication and treatment for this diagnosis.
Thank you in advance,
Barb
