Welcome to Healing Well. I'm glad you found us, but am sorry to hear that your dad is having complications after his surgery and now a cancer diagnosis. That's a lot to deal with in a short period of time. I wouldn't be surprised if he has a lot of anxiety over all of this.
I did not experience what you're dad is going through after any of my surgeries. Is he on any new medications or has there been a change in any of his medications? Is he drinking caffeine or eating a lot of sugar? Has the doctor done a complete blood work up on him?
I hope you get some answers soon, so he can get some rest. I will keep you all in my prayers. Take care and please keep us posted on how he's doing.
Dx'd Crohn's in '99 at 28. Proctocolectomy & ileostomy in '06. Remission since surgery.
Pain-free, med-free, and very thankful to be healthy again :)
