Hello, Thanks for posting on HCM, According your description, it will be appropriate to rule out a good number of causes that may be responsible for your symptoms. My possible impressions are that you are suffering from gastroesophageal reflux diseases (GERD) or acute oesophagitis or pharyngitis etc. Getting a doctor properly examine you physically and run some few tests could help determine the actual cause of symptoms. You might be suffering two different conditions which just happened to occur coincidentally (i.e may not even be related). Since you are already on a course of antibiotics, it is best to continue, but in order to handle the chest pain, your doctor might consider treating for GERD or acid reflux with PPI such omeprazole or H2 inhibitors such as cimetidine. Hope this helps
