Wait lists are unfortunately a fact of life. My only advice is go to the provincial wait list site and get your doc to send you to a hospital that has a short list. If its hip you may wait 18 months at Toronto Western but 90 days in London.
Also talk to your doc about a Cannabis or more accurately a CBD oil (drops) script. It will help with pain and inflammation but won't generate addiction issues or the dozy-stupid feeling of an opiate
