No the surgery seems reluctant to act
OK Richard. For this to have lasted as long as it has, while it still could be viral meningitis, there are other considerations.
You need an EBV viral titer drawn since you may have mononucleosis. But you also need the MRI of your brain to check for meningitis. Unfortunately, there is no specific treatment for either of those and they have to run their course
Unfortunately also, I am not your doctor so all I can do here is give you my thoughts that you can take to your doctor for discussion
Let me know if you need to discuss this further please
