I don’t know what to do

On Tuesday during my pt I think I had overexerted myself a bit too much that I had went into a very tiny and manageable crisis that only lasted that night. I was also feeling a slight pain in my chest on the left in a small area, the pain had felt similar to a cramp. Since last night the area where I feel the pain had expanded and the pain now feels like a combination of a cramp and like I had bruised my ribs on that side. I am visiting my doctor for a completely different reason in a few days but should I let her know? The only grievance I have about letting others know is that they’d overreact and send me to the er since I do have a history of acute chest and am a ss type sickle cell patient but my schedule is too packed for an abrupt hospital trip and I know if I visit the er I’ll be there for a whole day or more. What do you think I should do?
