Yesterday we had a sudden change in the weather here, and accidentally opened the window when I slept at night, and I got up hot today, and my limbs were very sore, and I took leave from the unit, and I took medicine and slept for an afternoon, although it was a little better, but my head was still groggy, I really didn't have the strength to write today, and I asked for a leave of absence, and if it gets better tomorrow, I will make up for it (to be continued.) )
