Kind of depends on the cause of the headache…is it sinus related? If you live in a dry area, your nasal passages may need hydration (netti pot or saline spray or take a hot shower) or it might be adult allergies. Is it tension? If so, try to find the tension and massage it out. Use peppermint oil roller (it cuts the intensity, but likely won’t make it go away). It could also be a good sensitivity that you’ve developed.
If you start I get them frequently or more than normal, keep a log of when you get them and what you did before it and what you ate. Then talk to your doctor. I spent three years trying to find out the cause of my migraines. Journaling can help.
I’m pretty sure your kitty is the reincarnation of my tortie who we lost in January. She looks almost identical. If this is the case, you’re going to love her. She was sassy, but such a loving cat. ❤️
