Last night before I went to bed I went to scratch a little bit under my arm and found that it was tender. Throughout today it has stayed tender, and now tonight when I touch it I feel a lump. I have allergies and they were slightly acting up today but I took medicine, and I'm completely unsure if this could possibly be related to that, but it's the only thing I can think of that was out of the ordinary. My cousin's girlfriend was over at our house last night and I think she was sick, and this morning when I woke up my throat was a little bit sore, would it possibly be an inflamed lymph node? I thought for colds your throat nodes inflamed, so I am entirely not sure... I don't have a cat so I know it's not cat scratch fever, and it is not really "painful" to touch, just very tender and sore when I push on it. What should I do? I have heard cancer under the arm is rarely painful so I am thinking hopefully it's not that, I just haven't a clue as to what it could be and I'm starting to panic again after a couple of days of being really good about not panicking... oh gosh.
