Hi. Thanks for your query. Read and understood your history of Trigeminal neuralgia and para nasal sinus infection. I think Prednisolone alone is not the treatment given in such conditions. Although it works immediately, I mean if it has to give you results, it will be seen within a day. I think you should an opinion of another Doctor, preferably an ENT Surgeon so that the proper clinical evaluation, examination and treatment can be instituted. I hope this answer helps you to get proper treatment. and diagnosis.
