There are reports of Pleurisy and sarcoidosis! Some have had reports of just pseudo chest pain that either went away or continued with no answer. I would suggest letting your derm know, though be advised they may not attribute Accutane as the problem. at 8 months 30mg you might consider stopping. Especially if your it has not helped your acne. Roche as even stated that the drug continues to work once stopping at least 2months -4 months.

Good Luck!
