This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
I understand your concerns.
Few reassuring points here:
You do not have any seizures, no facial weakness, no weakness of legs or arms, no problem with walking.
Now concerning parts of the headaches are--temporal area swelling, persistent nature, need for steroids like prednisone.
You also have history of autoimmune disorder like rheumatoid arthritis.
That makes vasculitis or inflammation of the temporal blood vessels more likely also known as temporal arteritis.
MRI of the brain is not that important although still needed to look for signs of brain vessel vasculitis related changes.
Hence, you need to consult with a neurologist for a temporal artery biopsy.
As long as you are on prednisone any further damage to th brain is unlikely soon.
It was my pleasure to help you today.
