It could be a form of costochondritis, it is not serious, but, finding out is a good idea as there are some things that can done to help the pain.
Hi katie9111,
If you have had a pressure that has not resolved, I think it is best to see a doctor to find out what it is. I know it's not fun to go to the doctor but since it has been a few months. i think it is time. Take care. :)
