I finally managed to get the courage to call the doctors today to see If they can work out what's going on. I put a post up the other day taking about my issues with palpitations and pains in the chest when I'm stressed out and I thought about asking the doctor about it. I have an appointment tomorrow with my doctor, they think it's stress and anxiety from talking over the phone but are willing to check me over to see if its anything serious. 

Thanks to everyone that told me it's best to get checked out, finally having something done about it.
