Abdominal Pain + Doctor Recommendation?

Since mid-November, I have been having upper abdominal pain (area right below ribcage in center of torso) and I am unsure what kind of doctor I should see to have them check it out. Here are some of the details of my ailment:

• Sharp pain at top of abdomen that seems to ease up when I reposition or stretch. Certain positions hurt worse (leaning forward definitely hurts more).
• Painful when I apply a little bit of pressure to it
• Even at times where it doesn't feel as painful, it doesn't feel like it fully goes away, almost like a presence.
• Breathing feels more labored at times
• Tylenol has helped ease the pain a lot
• Got bloodwork done in late November, most of the numbers seemed good and nothing out of the ordinary.
• Doesn’t seem to be connected to food, not thinking it’s acid reflux or GERD. Pain doesn’t seem to worsen when I eat certain foods. Prescribed an antacid by my PCP and it seems to not have affected anything
• Occassion inflammation around my ribcage
• Got rear-ended a couple months ago (Early September). Nothing too bad to my car, but I was jolted forward (airbags did not go off)

Since I'm leaning muscular/skeletal, would going to an Orthopedist or a Sports Medicine Doctor be the best?
