Car accident issues

My husband has pancreatitis and we got into a pretty bad car accident mid August. The day of the accident , he had a pretty severe attack. And post accident he said it spiked to a 10/10 pain. Now he's been bed bound every day since with attacks. It was normal for him to have an attack maybe once a month . I was wondering if anyone else had any experiences like this and how long did the attack take before it got better ? We did go to the hospital and we did a Cat Scan to which the doctor said that nothing was notable. We are going to a specialist soon but have to gather up all his medical documents before they will see us ( which is currently in process )

Also maybe worth noting that his pancreatitis is genetic and from the cystic fibrosis. He has had it since the age of 6
