Heavy migraines because of masking?

Hello, I (F21) have had really heavy migraines since I can remember. I don't even know how it feels to not have my head hurt.

Recently I've been told to look into autism as some people pointed out processes and things that I do that seem to be related to autism. I don't know if I'm autistic and I probably will never know because I'm too old to be diagnosed in my country.

I have found a lot of comfort in hearing autistic people share their experiences because I really felt understood. I started accepting the way my brain is wired a lot more and being more gentle with myself. And I also stopped forcing myself to hide things and trying to "act normal" around my family and friends.

Since then, my headaches are a lot less painful. Has anyone had a similar experience? Could headaches be related to masking ? Thank you so much for your insight !
