Need advice! Chest pain.

The last 4 days I’ve had a dull ache on the left and right side of my upper chest to the point where it was giving me anxiety attacks. I went to the ER and they did and EKG and a chest X Ray and said everything looked normal. When I checked My Health app through my hospital and looked at my results for my EKG it said in the comments that I had an abnormality in a t wave in V3. Should I get a second opinion? Or am I going crazy?? The chest pain is making me worry myself sick. I have a 2 month old that needs me.
