For the OP. Perhaps consider getting started in gliders. No medical required. Very good training on how a set of wings and controls handles in the air. And you can apply that training toward a power certificate in the future if the medical issues work out.
Drs. Chien or Fowler can provide you with more detail, but in general plan on 6-12 months of exams and work to clear your record and $5-10k, if it is possible.
