I would tell PT exactly what is happening and hopefully they can help figure it out - if they have no clue then they should ask a more knowledgeable PT on site..if more than one in the place.

Logically I would think some heat, massage and some manual stretches by them and no aggravating activities by you - meaning no weights or resistance bands etc.

maybe a check for trigger points and some e stim also.

trigger points can make some very odd things happen.
