Headache lasted 3-4 days. Weakness another 4-5 days.Brother I am so glad to read this post because that is the EXACT same thing that just hit me. My body aches and pain were so bad I went to the hospital, did not think it was covid because nothing respiratory at all. They gave me an IV and some pain killers which I needed really badly. Then they just sent me home with a prescription for nausea pills.
As with you, this headache is something I've never ever experienced. It's nonstop and painful to a degree I never could have imagined. There's just no end to it. I'm on day 3 now and it's only very very slightly gone away but it's still easily the most consistent pain I've ever had in my life. I just can't believe nobody has talked about this symptom more in the press.....
How long did it take for yours to improve?
And when I say headache I mean a lab created biological weapon targeting my skull. Entirely different than any headache you would otherwise experience.
Combined with the weird muscle cramps it felt like an engineered attack on the nervous system. My back muscles actually still haven’t recovered despite taking magnesium and stretching. Very deep knots I can’t get out.
