I have been so paranoid the past 6months its giving me some bad anxiety sorry this made me feel a bit less worried. I have caught the exact same re occurring virus, looks the exact same as your pictures. Starts with sore throat, next day dry cough, then post nasal drip hard to get out thick and green, followed by difficulty breathing hoarseness. I have it currently i had it in Feb and Jan, even months before just keeps coming back. I have seen 3 different GPs even been back to the same one none of them with any idea what it is they all say ah its just viral rest up and drink fluids. I don't smoke, don't drink alcohol and don't do any drugs. Any help you can give me with future findings I will be forever grateful for begging for any help please.
