Next day he had no more pain and the cough went away

My husband was coughing for 2 weeks and than complained that his lungs started to hurt. He also has asthma- and he never got tested for Covid- since it was no other symptoms. However after he said that his lungs hurt i prepared 3 drops of CD in a nebulizer ( probably gave him more than i should ) and he inhaled it. Next day he had no more pain and the cough went away. We are not sure what it was, but it did scared us- and CD made some change here- so we are all healthy and happy that  we always have CD  at home.  thanks,  Barb NOwacka
