Looking for a doctor who isn’t

Need guidance. My wife had 1 covid vaccine 2.5 years ago. 6 months later she had stroke like symptoms but no stroke. Her symptoms are light headed, brain fog, tumors, left side body tingling, extreme tiredness, head pressure and racing heart. We have seen many doctors including neurologist with no diagnosis or treatment. They say it’s made up but they have witnessed the tumors. We believe this could be long COVID or vaccine related. We are looking for a doctor who isn’t afraid to diagnose that if that is it and treat if possible. We live in southern IN but will travel if need. Any advice?
