What doctor should I see??

I’m a 25M, very active person. I hurt my back a month ago lifting weights to a point where I couldn’t move for a few days. Since then the back pain comes and goes with spasms in the lower back but now body just never feels right anymore and I have new symptoms everyday. If I eat something I feel like I’m gonna pass out, I can’t exercise it makes me feel sick and uneasy. Some days I don’t experience any symptoms but then some days it’s majority of the day.

I wondering if I did something to my back and I read that there are a lot of nerves that go along the spine. But idk if I should see a neurosurgeon or an orthopedic surgeon to help with what’s going on. My PCP wants me to do a stress test that’s scheduled for the 2nd week of January but I don’t think I can wait that long anymore the feelings are unbearable.

Please help and thank you.
