Sounds like they may have over worked and stretched you -
baby yourself for a week or 2 -
just some slow gentle movements and plenty of warmth if that feels best for you.
and see if that helps it.
i way over worked my forearms once and I thought I did my self in - i was sore for about 2 weeks.

But if you can get in to the dr do that also.

{I think that person was too rough on you - those with TOS, RSD, CMP & fybro, etc ALL need to find verrry gentle and expert therapists {IMO}
