Hello Sean, I am Dr. Arun and will be helping you today.The mold in the AC unit is not likely to be the only reason of the lymph node not going down in size or resolving. The lymph nodes many times may take even three to six months or more for self resolution. But yes many other factors can play role like allergies, upper respiratory tract infection, surrounding skin issue, etc which may prevent the size of lymph node to decrease significantly.. Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
Thanks for using Just Answer.
