I have a cough that started about 5 days ago, no fever, no nausea, no sinus congestion.I am cold and my back & stomach are sore from coughing. I do not have a headache, I do have some mucous and it is clear. Cough syrup does not help, tylenol eases the sore back & stomach. It does seem like I am coughing less; however, it is still very annoying and really makes me tired. Any suggestions? rlr
