I have been suffering from a sore throat, persistent cough (productive at times, intermittent between clear and green), lethargy, aches & pains throughout body - particularly in the neck & back for the past 11 days, sinus headache. I have been to GP who heard some minor crackles in lower left lobe of the lung, I ve had no temp, and nothing that warranted Antibiotics I am absolutely exhausted from all the coughing, unable to work and look after family, sleeping all the time and do not feel like I have had any improvement. Should I be returning to my GP?
