I'm 22 years old. 3 days ago I started getting pain under my left arm which I realized was swollen lymph nodes. Through the first night the pain spread down my arm, to my chest, and back. The best way to describe the pain is the sore/ache you feel when you regain feeling in your arm after it goes numb. The chest pain is what is worrying me, it is fairly constant on my upper left chest (above my breast). Breathing does not make it better or worse, mostly moving causes it to get worse. Touching my chin to my chest causes the pain to get much worse.
I went to the doctor 2 days ago and was told that the swelling wasn't too bad and since I didn't have a fever there wasn't much to be done. I mentioned the chest discomfort to him, but it wasn't as bad then so he didn't check it out.
I would just like to know if I need to go back to the doctor, or if it's something that will work itself out.
Thank you.
