Hi doc, I have been prescribed amoxicillan last week as my tubes were blocked in my chest however im still coighing and I get small pains in my chest?

Call doc! If you are no better after 3-5 days of medicine, then it might not be the right antibiotic. You may need an inhaler or steroids too. Call your doc or get seen and re-evaluated again. Avoid fragrances and aerosols as they are respiratory irritants and will prolong and/or aggravate your symptoms.
