Did you not see any doctor at that time?
I suppose you had taken T.T. injection then.
Do you have history of migraine?
Now how bad is your headache? Is there any episode of ongoing high fever
, fits, weakness of limbs
? About that throbbing vein that you mention you need to get it evaluated rather than just resorting to pain management.
MRI brain with contrast
Complete blood count
Just get these done and see a Neurosurgeon.
Get a proper neurological examination done and then take a call on whether you need any
MR Venogram ( MRV ) to be done.
Rest keep yourself adequately hydrated with plenty of fluid intake.
For headache first see if paracetamol
helps rather than resorting to strong medications.
