Hi just caught up with this post
Glad your headache has gone this morning, I used to have headaches when I was on mini pill then they went away when I started HRT, but one day I woke up with the most excruciating headache I ever had, left side temple over eye, I felt it was pushing my eye out! I took pain killers for days and nothing touched it. Went to GP checked me over said I was ok, nothing sinister, 6 days later after taking everything I could get hold of I bought forehead stick and used it all day long and woke up the day and headache was gone! Don't know if it was coincidence or it worked but I swear by it. If I feel one coming on I get forehead out and keep applying.
I felt done in after like you, tired, and as if I had just had head injury, no pain but strange feeling down face.
There's is a lot going around though.
