Thanks for query on HCM.
Treatment is on right way but if i have patient like you ,i would start antibiotic like amoxy with clavulinic.Amoxicillin
is first-line outpatient treatment in adults.
Also take levocetrizine/motelucast with ambroxal.
Take rebeprazole with antibiotic to subside stomach discomfort
syrup or tablet is advisable to improve the breathing problem.
Steam inhalation will be helpful.
Avoid to go in smoky,dusty area.
Keep in touch with your doctor.
