I have been having pain under my right arm and right side of the right breast. I also have been having headaches and quite a bit of nausea and upset stomach. This has been going on for over two months and this week I had a cat scan for a nodule on my right lung it was a follow up this has been going on for two years. The doctor wanted to see if ther was any change and I had a mamagram last Tuesday but havent heard anything yet. How long should I wait to hear?
