Dear friend, welcome to HCM!
With a
gall bladder problem, such constant pain on deep breathing could be due to a gall bladder pathology or others like early
pancreatitis.
Especially if it is increasing with deep breathing, dull aching, constant pain, also going to the back, we should look at the
pancreas.
You will need a good physical exam and labs (like serum
lipase, LFTs) and USG to elucidate the cause.
Is there any
nausea, fever, fast heart rate?
Please be guided by your doctor if there are positive clues.
Take care and please keep me informed of your progress.
Good Luck!
I hope to have answered your query satisfactorily.
Thank you!
