noticed a small tender lump about 1.2 inches down from my clavicle on my right chest also the vein passing in this area is raised and noticeable both down into my right breast and up to my neck this does not usually show. I have just come out of hospital as an emergency admission last night for central chest pains. The hospital have diagnosed viral chostochroniditis. I also have bilateral tender lymphadenopathy of the submandibular glands a sore throat and a cough which produces green phlegm and causes a great deal of pain.This lump was not present during my stay in hospital. I am still feeling very unwell with the virus and I am taking regular paracetamol for the chest pain and temperature. Highest temp 37.9. I get tired really quickly and feel out of breath when walking also the chest pain increases on walking etc all of which the hospital where aware. The hospital discharged me saying to take regular parcetamol (very sensitive to aspirin and nsaids cause severe stomach pains) and bed rest until I feel better, I am also sensitive to penicillan (rash) oxytetracycline (rash) erthromycin (shortness of breath) Clindamycin (tongue swelling). Do I need to see my GP regarding the newly noticed lump or is this part and parcel of chosttochronditis? Thank you for your time.
