Shane,
This is a good answer from Will. Sounds like it could be coming from your back too. I would suggest standing, and walking whenever possible. Sitting too long can really jack you up just like standing too long hurts as well. It’s very dependent upon what is going on in your back and hip.
The back pad posted above, has been and is a savior for me, been using this for 4 years ever since I started the path to a healthy spine. Even in my car with a lumbar support adjust build into the seat, this bad is necessary for me.
Going the the chiro is great but you have to address the structural issues ie corrective work. This takes some learning but is easily done, esp with the books below. Super easy.
Lastly – get educated. 2 books every athlete should read concerning the spine and health esp if you have issues
