Flare or no I recommend that if you are having any type of chest pains that you seek Emergency Care. IMHO if you begin to have chest pains that continue and worsen etc then seek medical attention.Even if you had been seen by a Dr for this symptom if you begin having worsening,severe pain in your chest you SHOULD be checked to rule out anything dangerous going on.
Honestly I am not trying to be rude/freak you out/cause you alarm * I swear * but You could be having a heart attack or some other severe issue.Regardless of age,diagnosed illness or not and women present differently than men and people vary wildly in their symptoms.Some aren't even aware they have had one until they have another.
Chest pains are nothing to mess with especially ones that are WORSENING.Please get this checked.It could be nothing but it could be something!I would want to make sure it's NOTHING.
Be well and please get this checked.
