I have a cough that will not shift.
I caught a common cold three weeks ago and had a cough that doesn't seem to go away. My upper chest feels very tight and I have terrible bouts of coughing fits that get worse as the day goes on. Tried different cough mixtures.
It is not uncommon to get an infective cough and associated rib strain which can go on for weeks. Often this starts with just a head cold, which then progresses to the chest with forceful bouts of coughing. Most often the upper airway and nasal symptoms are caused by a respiratory tract viral infection and will clear in time, but if the cough is worsening after this length of time it may be that you have a bacterial infection which would need antibiotics to resolve. If the symptoms are worsening after three weeks I would certainly recommend you see your doctor to get checked over. If you have a wheeze or associated shortness of breath it is possible you could also have asthma, which can come on at any stage in life.
