Any wound on the body will hurt. And depending on the severity of the injury, you can experience pain flare ups, aches, sharp twinges and tingles, itching and burning sensations until it eventually heals. And you’d think nothing of any of that.
The brain really is no different in that respect. So the sooner you can to relax, accept and pace yourself the better for taking pressure off your brain and allowing it to heal 
Keep up with your medications and physio, a heathy balanced diet with plenty of protein if you can. And that’s about all any of us can do to avoid another one.
Welcome to the forum @Seddso, so sorry you’ve had to join us, but its a very good place to start your journey to recovery.
I started taking magnesium glycinate for my head pain about 2yrs after my stroke, I’m 4yrs post stroke now. I’d had further investigation done, including mri and CT scans, about a year after my stroke and they came to no conclusion other than the effect of the stroke. Pain killers did nothing for it but the magnesium did work to relieve it. So I continue to take a daily dose as the pain dose come back when I stop.
Thats not to say that your head sensations are the same as mine or will last. Many do cease in time, the first 6 months see the most recovery in the quickest time, it slows down after that, but doesn’t stop. But if you do decide to try Magnesium Glycinate, do speak with your gp or the pharmacist you get your prescriptions from first, to ensure it doesn’t clash with other medications you’re taking or other medical conditions you may have. I’m not a qualified expert, I’m only experienced in my own stroke condition
