I've been feeling very tired lately, sleeping early at about 10pm, and then waking up at about 7am. At times, I sleep even earlier, by 9pm, or 8pm.
And whenever I wake up in the morning, since before the Macau trip(Days 1, 2, 3, 4), I would feel an ache, a pain, slightly below the neck, at my back. I've been feeling sluggish as well. I have no idea what's happening.
One good thing, the heel pain seems to be gone though!
