Spreading numbness in head and face.

I've been facing this problem since the past 9-10 days. The numbness spreads from behind my ear to the top of the head, only on one side at one time. But it has happened on both left and right sides of the head. The numbness remains for sometime, around 30 seconds or so, and then disappears. Today I have also had problems such as problems with concentration, foggy mind and slurred speech at the very end of the sentences. Also there is very mild pin and needles feeling allover my head and near eyes and ears. I have booked an appointment with a neurologist tomorrow, but should i wait until then? or should i go and get checked today itself. Will taking anti-inflammatory medicines help? as I have always had swelling and pain on my neck and shoulders and i believe some nerve is getting pinched due to the same swelling.
