I understand your concern.
Well as you describe,your symptoms are not related to rabies and you have already taken 4 doses of verorab so I definitely assure you that chances of developing rabies are very less to negligible.
Possibly your symptoms can be associated with viral infection.
Your tingling sensation and pain radiating to leg can be associated with nerve compression in it's path.
So you should do gentle massage with muscle relaxant ointment.
Do leg stretching.
Take OTC Motrin,Prilosec.
And see your doctor for further evaluation and management.
Sometimes headache,muscle pains,nausea are adverse effects of vaccine and last for few days.
Let me know if you have any further query so we can discuss it thoroughly in every aspect.
Waiting for your response.
It’s my pleasure to continue this conversation until you satisfy.
