Tightness in one side of head

I’ve been referred to neuro for investigation, but my GP thinks I’ve got a several indicators of MS and I fit the most common profile (female, 30s).

By far the most bothersome to me is the tightness in only one side of my head. If feels almost like my brain is being squished, whilst simultaneously that the outside of my skull is too big and disconnected from the inside. It doesn’t hurt as such, just feels so uneven compared to the other side (which feels totally normal).

This has now been ongoing for months and I’m so tired. It’s not really a pain, and OTC painkillers do nothing to ease the feeling.

Does anyone have any suggestions about what has helped them deal with this?

Many thanks for any suggestions.
