I've been experiencing some chest pain for the past few days. It moves around - sometimes on the left side, other times on the right. I'm not sure if it's muscular pain or something related to my chest rib cage. I dont have any issues with breathing and there's no cough either. I've tried deep breathing to see if there's any discomfort, but it doesnt hurt when I do that. I had a chest X-ray just last month and everything looked fine. I do have a deficiency in Vitamin D and B12. Could this be related? What's your take on this?

Salbutamol inhaler and budesonide 200 sos is advised for breathing difficulty.
