Do i have to have lung problems or gallbladder problems just because i experienced a weird burning sensation in my right chest under the rib? ideas?

Not necessarily. It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see a doctor. Wish you good health!

A 'weird burning sensation' is not really enough info to make a diagnosis. Did you injure yourself? What are the triggers? does eating change the pain? Breathing? Do you have fevers, cough or other symptoms? Was it a fleeting pain or does it continue? is it constant or does it come in waves? A physician would need a LOT more info to help you. Please see some one if the pain continues
