I noticed a hard lump on my left breast and a few days later that the lymph nodes under my left arm are swollen. A few days later I started to get a dull ache across my collarbone. Upon inspection I have a swollen lymph node there too. Tonight when my dog jumped up, her paw pressed on my groin which was painful, so I went to touch and have now noticed a swollen lymph node there too. All of these swollen nodes are on my left side (not sure of this is relevant). I am currently abroad so don't really want to visit a Dr here but obviously will if needed. Is this normal? I've had a swollen node in my throat when I've had strep but never this extreme with no apparent illness. Can anyone chime in with some similar stories/advise?
