I have noticed a lump right above my collar bone by my throat. It is hard but moves around just little bit. It has hurt some in the past 24 hours more specifically. In addition to this, I have noticed that I have been feeling sick a lot more lately. I usually have a headache almost every day and also have noticed a lot of nausea and my throat feels uncomfortable to swallow (but doesn t feel sore), There is also pain in my shoulder that this lump is close to and I have been very very tired these past few weeks. Additionally my chest has been itchy and I ve been scratching so much that I even have cuts on my chest. What could this be?
