What could this be?!

What could this be?

For the past 2 nights I have gone to bed with the most unbearable pains in the right side of my chest. They feel like muscle spasms but worse. It starts above my breast with a tightness and then goes down toward my arm pit and then up my shoulder blade and into the top of my right arm. There's a burning sensation in my right shoulder and forearm during the day and I find myself become short of breath while working, talking, and just doing everyday things. It's almost like I have pressure on my chest.

Also, I have noticed for a month or so, I have these headaches out of nowhere with the pain is directly on the top of my head. A few minutes later I will get extremely dizzy for 3 minutes or so. I have not passed out from one of these and it does affect my balance tremedously.

I exercise regularly. I do not smoke. I do not use drug. I am taking BC and Prilosec regularly. I eat heathly. I have a doctors appointment in the morning. I just wanted some opinions on what I should expect when I go. What do you think this is or what causes it? Thank you for your help.

Sounds like heartburn , maybe from the BC.
Take pepcid Ac before u take the BC.
Eat strawberries for dizzy.
It may be indigestion, (air) Do side stretches, it will make u burp air up.
top of head----is the reflex point for the chest.
Rub the head good with middle and pointed fingers, massage the pain out.
This could also just be an allergy for dry pollen season.
Anyway...try to find a natural cure...http://www.reflexology.com
