Good morning SeanH!
Welcome to our forum!
Sorry to hear of your pain! Were not Dr's here, but will support you as needed. One thing you might try for the constipation would be Prunes....they are all natural...and should help. Also stick with a high fiber diet if possible, and if your problem persist, then by all means get in to the Dr, and don't let this problem go too far. There is always a chance of a twisted gut....and that can be very serious to say the least.
Make sure you keep plenty of fluids down....and if you do not see a difference in bowel movement...then as I said get back in to your Dr immediately.
Please check back in with us, as it may help others who may be experiencing this same issue, and they may benefit from your information.
Take care,
SE
