I'm really worried about my mom. She's been having this pain on the left side of her chest, and it spreads to her shoulder blade and down her arm. It's been really tough for her because she also feels uncomfortable when she's swallowing, and the pain gets worse when she takes a deep breath. She's not dealing with a cold, cough, or fever, but even with the meds she's taking, nothing seems to be helping. Could you please help me understand what might be going on and how we can treat it?
