Strange Lump in Armpit

On Thanksgiving day I was in the shower and noticed a painful lump in my armpit. It was tender to touch. It was under 1cm big and the skin was red on top. In about 2 days the pain went away and after a few weeks it went away completely. However, my arm pit continued to ache on and off. Not much pain just an annoyance. Then yesterday my armpit was hurting a little more so I felt under my arm and the lump was back. Sore to touch under 1cm. I have never had anything like this in my life and have not other symptoms. Does it sound like an infection and why would it go away and come back. The lump entirely disappeared the first time. Any ideas? I am a 45 year old male by the way.

Lymphoma typically causes painless (and progressive) enlargement of one or more lymph nodes. On the other hand, tender, painful lymph nodes are usually caused by infection or inflammation.

Unfortunately, it is not possible to provide a specific diagnosis over the Internet to patients with concerns regarding enlarged lymph nodes. Therefore, my advice is for you to see your doctor for an examination. If you have persistently enlarged lymph nodes (and especially if they continue to enlarge), then a biopsy may become necessary to rule-out lymphoma, or other cancers involving the lymph nodes.
