Not a medic so won't comment on your symptoms. My advice to you would be to contact an AME (Authorised Medical Examiner), you can find a list on the CAA website. I would make an appointment with a Class 1 examiner near you, explain the situation and see if they can advise you on how to proceed.
You will have to pay for their time but it will be a lot cheaper than applying for an initial Class 1 which is expensive but something you will have to do at some point if you want to start training.

Good luck.
