Well if your pain was relieved once with therapy protocol. I believe you can reduce it again.
But you will need to get yourself physically eveluated once again to find out if the same pain that has arised due to weakness or something new.
More or less as per your description it seems to be weakness playing its game, but its better to be sure and if that is the case take some more sessions of physical therapy
and this time I would ask you to be regular with your exercise routine.
There won't be any time in your life when you will be free so take out time specially for youself and make yourself healthy.
Hope it helps, Take care
