My son has had chronic cough for four months, repeated episleritis, negative allergy test and low IgM value. What does this indicate.?

Episcleritis: Your son needs additional evaluation by an eye care specialist. Recurrent episcleritis (when we are able to find an associated condition) is most often related to autoimmune disease. The negative allergy test and IgM levels are not too helpful in my opinion in regards to working up the episcleritis. ...Read more
