Help! Confused about Insurance

I'm a student in London on a 3 yr visa, and have done something to really mess up my back. I'm in a lot of pain and can't use the left side of my torso/upper body so I decided to try and find a chiropractor.
However, I'm really confused on how much I will have to pay. I paid for National Insurance when I got my visa but since a chiropractor is private I know it's not covered in that payment.
I'm also listed under my parent's Blue Cross Blue Shield but don't know what the international options are.

Does anyone know what my options are for insurance coverage? Has anyone used their US insurance while in the UK?

Thanks!

If you want to use a private doctor, you'll need to find out what their rates are.

You'll also need to find out about your specific policy that you have for international insurance.  They are all different.

Feel better.  You could always see your regular GP or go to an urgent clinic for a treatment plan (at no out of pocket cost)

Yes, go to your GP first. Sounds dreadful.
