And I'm concerned about my post concussion syndrome.

The twitches are kind of like convulsions. They come on most notably when we are going to sleep, and throughout the night. My SO's head jolts, and shoulders do as well. We don't know the cause - my partner has this and a host of other health issues doctors have been unable to diagnose.

For this reason, I'm wary constantly at the idea of them hitting my head. It's even to the point where I resist cuddling for this reason. I haven't brought up my concern, I'm very sure my partner would be offended - they've had trouble understanding my PCS related issues in the past.

Should i really be this concerned over this? Am I being over anxious? Or reasonable in my worry?

Any insights or advice you can offer would be greatly appreciated.
