No worries. A good physical therapist is more than just a person to rehab injuries. I use mine for any chronic issues I’m having, especially if they don’t seem to be worsening with activity, and they are mostly uncomfortable/a nuisance. In most states in the US (as far as I know) you can see a physical therapist without a doctor’s referral. So, personally, I see mine when I have the money and I just can’t figure out what to do about something.
A good PT has a good understanding of biomechanics and injury/healing etc, and as such, they ought to be able to help you figure out if you could be moving differently in a way that could alleviate your symptoms. Sometimes we have restrictions in ways we aren’t aware of, and by addressing those restrictions we can alleviate uncomfortable symptoms we are having. Sometimes we aren’t using a muscle group in a way that might aid out symptoms, etc
I have to agree here. I briefly pursued an exercise science degree (similar to and ex-physiologist) and didn’t seem to be learning anything I couldn’t learn elsewhere. An exercise physiologist will learn stuff like anatomy, metabolic progresses and the like, and basic programming regarding training (most of which you could learn for free online with some effort). At least that was my impression.
A physical therapist will likely have a lot more knowledge with biomechanics, specifically, as well as the training to work with things like arthritis. Again, try and find one that has successfully worked with people with your specific issues if you can.
Edit:FYI many physical therapists have CSCS certifications as well (certified strength and conditioning specialist).
