If it is taken for time being then it is okey, but should not be taken as treatment for
shoulder pain. Shoulder pain has to be diagnose properly and should be treated accordingly. I am sure the
physiotherapy treatment what she is taking will be according to her diagnosis and will help her to get relief.
You can also ask her to use hot and
cold pack frequently to get some more soft tissue healing with relaxing soft tissue, increasing blood circulation, and reducing inflammation.
Here just wanted to update you to check whether she has
frozen shoulder or its a soft issue damage (
rotator cuff) .because many times it is diagnose wrong and treatment for both is different.
For frozen shoulder more over as a physio I do treatment with shoulder manipulation. And for
soft tissue injury the manipulation is not suggested and only the soft tissue relaxing and healing treatment only can be given.
To check if your mother able to move her hand up standing against wall as well take hand on her back with little pain then it is related to soft tissue pain.
And if she is not able to move hand up complete with range block feeling then it can be frozen shoulder.
If still confuse then still can be diagnose properly with
MRI.
Here my only advise is treat the cause of the pain and painkiller should be for time being.
Hit the thanks if it is useful. Take care.
