The same situation you describe " pulse elevation and chest pressure" happend to me 3 year ago.
Raising up the Prednisone solved the problem.
I don't thing your problem is "stress".

I now get a mild nausea that stays around so I eat small lite low sodium meals through out the day. I also have surprise chest pounding with my head getting tight. I walk around the room to exercise it off. I now have more trouble sleeping because I wake up several times. I get very sleepy at times during the day where no amount of coffee will fix the problem.
A chest x-ray is cheap and will give you a lot of information. Any chest heaviness and shortness of breath needs to be examined ASAP. I would put off the colonoscopy until after a chest x-ray. A chest ultrasound of the heart would give you an assurance of exactly what is going on with the heaviness.
I hope you get the answers that you need. I will put in a prayer for you. Please keep us posted.
