hiv symptoms armpit lump

Does lump in armpit necessarily has to be HIV symptom? What else can be cause of armpit lump?

There are various causes for lumps in armpit. They are not necessarily symptom of HIV. I had once armpit lump and it was lymph node which was enlarged due to bacterial infection. Different viral and bacterial infection can be cause of armpit lump. Ask for professional help if you have lump in armpit. If is helpful to know HIV related lymph nodes are non tender there are always many of them, not one.
