Yes you should see a neurologist.
Sometimes specific medicines in this situation can prevent the headaches, particularly if it was post meningitis induced.
I don't think muscle spasms in the chest or back are directly related to this, and that should receive further investigation as well.
For example low magnesium , thyroid
problems, or other conditions can predispose to muscle spasms.
However, I suggest you present all of this to the specialist.
OK. If you have further questions or details, use reply to expert.
Otherwise please choose a positive rating . But, still come back if you need to…think of something later, etc. Bonuses are appreciated.
