Go see your doctor, I am having the same issues. My gallbladder is not working correcly, It happened out of the blue. But there are a few things that could be going on. Your doctor will draw blood and do test to find out. Good luck.
I dont have ashma nor have I had a cold recently. Just a sharp pain in my area under my breats/rib and only the last week or so.
There are a few organs in that area that you might consider checking out. Your lungs as well as you gallbladder can cause pain in your lower chest and back. Have you had a cold recently or do you have asthma?
