Given your wife's medical history, I would take her urging and head to the doctor to see what the issue is. It's impossible to tell you for sure what is happening based off of a brief post and description- your doctor is going to need to see you in person and gather a bit more information on your personal medical history. I now doctors are not fun and it can be difficult to decide to go see one- but listen to your wife and go ahead and get to one.
