Pain on left upper chest below arms.

My mother is a stroke patient. She had 3 series of strokes last year due to hypertension m. She is ok now but needs support for walk etc. she is complaining pain on left upper chest. Her BO is normal and all other parts are fine but she says the left upper chest below her arms pain if there is much movement or if touched. What could be the reason and do I need to consult a doctor? I am not in favour of taking her to hospital due to covid risk and I don't have a car. I had done video calling with the doctor who saw her at Sakra during stroke and she was fine. This is a new problem that started just a day ago. I also want to see if there are doctors who can do home visit to see her if necessary.
