2 years ago i caught some repeated strep throat infection, repeated like 6-8 times - because my original general doctor said that with low CRP there is no way i have bacterial infection... before i found a doctor who finally did proper swab and ABTs - but i was so far gone that i got horrible headaches, muscle pain, stinging, absolute weakness... on top of that i cought covid and proper flu. Totally crazy, when they did mi vitamin D it was at 10% of minila recomended value. I god vit D and some immunity pills(pigs blood cells - this is questionable). I was slurping the vitamin D every day and in couple of weeks I was almost back to normal.

I have seen neurologists, imunologist, infection diseases specialist, everything is boreliosis qack and even somatic doctor...

Funny thing is before i got sick i spent 3 months on tenerife, so no reason for me to have low vit D. But it was probably depleted by immunity trying to fight the repeated infections.

so yeah, get your vitamin D checked if you feel weak, low on mood or anything out of zen
