Not a guarantee of no damage but if your bike didn't have any bent wheels, handlebars or other bits on the bike that were bent or severely twisted out of place there is a very good chance the bike is fine. Pretty easy to damage bar grips and put some minor scrapes in a fender without doing major damage to anything else. My thoughts are with you and hope you make a total recovery and back on the bike again, it sounds horrific. Have you checked to see if there may have been any cameras that may have recorded your crash. It would be good to know if maybe you were attacked or just lost consciousness while riding or maybe you were just trying to avoid a pesky squirrel.
