i was given prochlorperazine to combat the symptoms of dizziness and nausea when i had labyrinthitis and it did work quite effectively. mine cleared up in about 10 days and i know i felt absolutely awful - i can't imagine how fed up i would be if i had it for as long as you - you have my sympathies and best wishes! as stated previously, your existing medical conditions and prescribed medciation may be affecting your symptoms and length of recovery, but i really don't see how your dr can leave you feeling so rubbish. there is treatment out there for you - tell him/her so! good luck to you and get well soon x
