The ones that tend to hit hardest are deep full-body aches, crushing fatigue that no amount of sleep fixes, nausea or actual vomiting, pounding headaches or migraines, chills, dizziness, and brain fog that makes it hard to focus. Add cramps and bloating on top and it's a lot. Some people also get hit with low mood or anxiety that piles onto everything else. None of this is something you have to just live with. If any of these symptoms are severe, lasting more than a few days, or getting worse cycle over cycle, please loop in a healthcare provider. Real fever, fainting, or vomiting you can't keep down warrants medical attention.
