It seems from the history that you are having pulsating headache in the left temple. The first disease that has to be ruled out is temporal arteritis
. You require systemic evaluation if you have other symptoms like general fatigue, weakness...
The treatment with prednisolone
is required for temporal arteritis also but it is required in a higher dose.
The treatment with steroids
is very much essential to prevent potential complications associated with it.
Hence I advice you to consult your doctor preferably a neurologist
for examination and treatment accordingly.
