I've been experiencing this sharp pain on my right side just below my rib cage. It feels like a pinching sensation, especially when I take a deep breath. A couple of days ago, the same area was really itchy, but it felt like it was deep in my lungs. I can't figure out what's going on because I don't have any other symptoms like fever or body pain. I did have a cough and cold a few days ago though. Could this be something serious? What might be causing this?

Ecg and x-ray chest pa view is advised to the patient.
