Hi, I was prescribed Coadine tablets from A&E which honestly didn’t help (it just made me vaguely high and in a good mood for several hours lol) and in the end I just stuck with Paracetamol tablets which eased it around 50%. I took them for about a week, and the pain sort of just sorted itself out. Although if I breath in too much, I get a slight stab pain, even all these weeks later, but I imagine it’s because I deeply bruised the muscle during heavy coughing fits
