Too cold for me to walk or cycle at night. If you continue to have very bad headache, I think you should see the doctor. Have a blood test (D Dimer test) for the evidence of micro blood clots. The Covid vaccine caused the micro blood clots, it could be quite dangerous. A few villagers had already been hospitalised and had operations.
