I've been diagnosed with sinus infection, but I also experience pain and numbness in may arm and leg.?

I don't think your numbness in you arm and leg are connected to your sinus infection. You need to tell your Dr. about that and it is very important that you do.

I do not consider you're over reacting. If you do not consider correct, you should be listened to by means of your general practitioner. I have heard approximately a situation referred to as Guillian-Barre Syndrome that has probably the most signs you're describing. It can come approximately hence of an endemic and mostly from vaccines. I could see your general practitioner and demand they run a few assessments. Pain and numbness to your extremities will have to now not be unnoticed. I desire you well good fortune.
