Hi there!
Continued symptoms do not necessarily imply that the infection persists or that the antibiotics were ineffective. The symptoms could point towards other causes such as continued inflammation, GERD, superadded GI infection, chest wall inflammation etc. You may consider a review with your treating gastroenterologist for a detailed evaluation and suggestion of an appropriate management plan.
Hope this is helpful.
Take care!
And nausea started today.. Anyone has any idea why?:(
