Hello @tatianac
As others have said, I too encourage you to seek medical attention immediately.
Canadian medical care is far less expensive than American because it is backed by the government.
In Canada, medical care is a human right: no one should suffer grave injury due to lack of funds.
If your presence in Canada is a legal matter, all medical care for those detained under the law, is completely covered.
When you present yourself to the Emergency room, ask to speak to a Social Worker, who will assess your situation, while emergency care is given.
Whatever life situation you are in, everything will become more complicated with a permanent injury.
Only you can assess the risks: but your physical needs sound urgent.
I wish you the very best in dealing with this matter.
Please let us know how you decide to proceed, and how everything turns out.
