I Was Stung By A Small Beige Scorpion At 1040

I was stung by a small beige scorpion at 1040 pm last night. Immediate intense burning pain on index finger. Within 2-3 hours numbness moved up to mid lower arms then migrated to feet and up right knee Difficult to stand with all pins/needles feeling. Eyes were flickering so was hard to read. This am all same but face feels like I had received novacaine at dentist. How long will this last.
