I need to find medical consultant who will work with my case

Hi! I am not asking for members to help me find a particular doctor, rather I am asking for members to help me locate medical consultants that in turn will help me find the right doctor.
1. Age 42, male, height- 5′5″, weight-143,3 lbs., non-smoker, living in Texas.
2. As far as symptoms, they are due to medical treatment that was for childhood Hepatitis C, as in all symptoms began during treatment and now remain (excessive exhaustion, severe brain fog, constant lightheadedness, memory issues, photophobia), although Hepatitis C is no more after treatment.
3. Treatment began in 2016. I was treated for 3 months with Harvoni.
We have seen a few doctors for the issue, they have ruled out autoimmune, and MRI showed to be normal (as per doctors), and after they rule certain things out they simply let us go, that is why we are asking for a Professional Consultants who can advise which specialized doctors are because doctors just dropped the case, so Professional Consultants who will take the case and will lead the case with the goal of actually helping us take the case to a certain completion.
