Suggest Treatment For Swollen Lymph Nodes After Treated Sinus Infection

Hi, I m 34 female and 105lbs. I ve been sick like many much of the winter. I was on a zpak two weeks ago for an acute sinus infection that went away about five days later. Now I feel healthy, but I ve started feeling asthma symptoms with breathing and coughing when I go to bed (mild) and I ve discovered my right lymph node under my ear is swollen and feels like a marbly muscle and I have a pea sized painless lump on another part of my neck on the right side above my collar bone. I discovered the latter a few months ago, but then forgot about it. I ve been sick so much with infections and colds, it may just be something that comes and goes, I haven t tracked it. It also could have been there the whole time. I also have something on my arm that popped up around the same time. It s nobby little lump I ve pretty much disregarded due to location. Anyway, I don t know what to think. Is this cold related or something I should be more concerned with. I ve had my share of doctor s offices this spring. Thank you.
