Thanks for your question on Healthcare Magic.
I can understand your concern.
No, possibility of relapse of Hodgkins disease is very less.
Possibility of bronchitis (inflammation of airways) is more likely.
Bronchitis causes
bronchospasm and this in turn causes
chest tightness, cough, breathlessness etc.
So better to
consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).
PFT will also tell you about severity of the disease and treatment is based on severity only.
You will mostly improve with inhaled bronchodilators (formoterol or
salmeterol) and inhaled corticosteroid (ICS) (budesonide or
fluticasone).
Don't worry, you will be alright with all these.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
