Yesterday started having sweats and chills, both alternately and sometimes a t the same time. Skin was clammy and experienced slight nausea. Tongue twice had odd feeling which went away in a short time. Had been installing window air conditioner and had air blowing directly in my face while installing same. These symptoms lasted through the night, alternating between chills and sweats, and as mentioned before sometimes at the same time. Pulse ox normal and temp is normal
