Suggest Treatment For Swollen Lymph Nodes In Neck, Armpit And Cervix Area

I seem to have swollen lymph nodes in my neck, armpit and my cervix area. I am always coughing up phlegm and always short of breath. I have taken many different antibiotics and it just keeps re-occuring. It's been like this for almost 3 years now. I seem to get alot better with my antiobiotic and then it takes about a month before I go through the same thing. Occasionally when I wake up, I vomit due to so much fluid and thats all that comes out. My stomache usually feels bad, almost turned and I am either sweating or cold, its hard for me to be comfortable. I get weird headaches that aren't usually painful they are just kind of there. My face feels pressure to the point that my eyes start to water and my ears hurt. I feel congested all the time. I feel sick in general all the time unless I get an antibiotic which doesn't last for long. I'm wondering what the best thing to do for someone in my situation would be. Thank you
