Angina or any heart problem doesn't only affect older folks. I'm glad your going to have a stress test done as that is how they will know. My husband had slight chest pains and a bit of short breath in Nov. but let it go due to us having a cold. Absolutely nothing that bad to think heart attack.
When I saw he wasn't getting any better after days in bed resting I took him to the ER. They admitted him for observation and were going to do a stress test on monday morning. During the night his Troponin levels went up indicating something was wrong, even though in ER he had blood work..EKG and chest X-ray, all normal. They skipped the stress test and did an Angioplasty and found he had a blocked artery. Dr. said had he waited another week he probably would have had a full blown heart attack.
Never ignore chest pains or try to shrug it off as being something else till it is checked. Yours could be nothing, or it could be angina, but best to have it checked now. You want to be around for that baby for a LONG time.
Best of wishes, keep us posted...JJ...
