I'm feeling this weird vibration in my right lower lung when I breathe, mostly at night when I'm trying to sleep. There's no pain, just this funny sensation. But sometimes if I take a deep breath or move a certain way, I get a sharp, needle-like pain. It's growing concerning, and I'm wondering what's going on. Can you shed some light on this?

The vibration and occasional sharp pain you feel in your lower lung could be due to muscle strain, mild inflammation in the pleura (lining of the lungs), or even trapped air in small airways. If it persists or worsens, consult a doctor for a thorough check-up to rule out any lung or musculoskeletal issues.
