<s>[INST] Hi, I have had a pretty bad cough and cold, possibly flu for the best part of a month now, which has pretty much resolved, but I now have a pain on the left side of my back, level with the lower part of my scapula.  This is worse when I cough or breath in and seems to be going into my left arm.  I dont feel as if I pulled anything whilst coughing.  Any ideas what this could be?  Many thanks, Wendy [/INST] HiT hank you for asking ChatDoctorI have gone through your query. Possibilities for your problem can be muscle strain from excessive coughing or irritation in lungs. Better to do a lung auscultation to rule out any problems relating to lungs. If that is clear. Then taking cough suppressants, antihistamines and local hot fomentation will be helpful to clear your problem. In case of any positive lung signs on auscultation then chest x-ray will be required. Hope this may help you. Let me know if anything is not clear. Thanks. </s>
