Pain in chest

I sometimes get pain in my chest, Like pinching or stabbing. It catches me off guard. I have a small ulcer that I am taking medication for. I also get a little anxiety from time to time. I also have some pain around my collar bone. This could be that I have had a bad cold and have coughed an awful lot in the past few weeks. I am on antibiotic.Really just the chest pain and sometime rapid heart beat has me concerned. I am 44 years old and a female going through what the Dr. says is perimenopause. Just looking for a little advise.

Thanks

Yes i have talked to my Dr. Many times. He tells me it's not my heart. I had an EKG and chest exray last year which came out fine. My cholestrol is 145 so that is good. I work out at the gym 5 days a week. Take a multi vitamin and other supliments as well. Vitamin D, coral calcium,green tea, folic acid, I have told my Dr. all of this as well. it really comes and goes. maybe it is indigestion or something. I have physical yearly so I really do keep up on things. I guess as I'm getting older I just feel more aches and pains in my body which bothers me. It's nice to just vent to someone about it besides bothering my family all the time. Thanks.
