New possible MS symptom?

Hi! I have been experiencing tight chest, chest pain, and shortness of breath for 2 months now. I was thinking it could be the MS hug but it doesn’t usually last this long right? It has been on and off and recently started to get a little worse. Could that be what it is? I have gotten an EKG to make sure it’s not my heart and that was normal. Is this my MS or no?

It could be MS Hug; or it might be something else. I am assuming you have been checked thoroughly for chest infection(s), asthma etc.?
