I had a cat scan done and it said that i have mediastinal lymphadenopathy, and will need another cat scan in a month. I've had a cough for several weeks and not feeling up to par, and I went to the hospital because of chest pain which seems worse at night, and thought that morning i was having a heart attack, they say my heart is fine, but i have 8 enlarged lymph nodes. The pain and discomfort has eased up, but when I drink and liquor the pain in my chest seems worse? Any ideas on what it may be?
