Sorry you feel so bad,Ann.
I've heard others on this forum mention the head squeeze
feeling,but don't know what that is.
Did you still have all the other precautions at the dentist?
After my previous dentist visit,I felt great for about 3 days &
then felt awful too.It could be a positive sign that you're detoxing...
Remember that you need time to recover after the dental work,it can take more out of you than you might realise,
especially if you're not feeling 100%to start with.
take care .
