I worked out Wednesday evening including 10x3 bench pressing and woke up Thursday morning with swollen, tender, and slightly red lymph nodes in my arm pits. I thought it was a bit odd because I've never had that happen before.
I did a bit of reading on causes of swollen lymph nodes and the main cause is fighting an infection or an injury to the body near the nodes. I still feel fine today so I dont think I'm fighting an infection and I havent had any injuries lately so I'm a bit stumped.
I asked our nurse at work today and told her I worked out pretty hard bench pressing the night before (PR on the 10x3) and she said that was probably the cause. She said I probably worked the muscle hard enough that the breakdown of the muscle fibers may have been severe enough that it caused my lymph nodes to swell. I was sore the next day but not overly sore, in fact my hampstrings hurt worse from my Rom deadlifts than my tris or pecs from the benching.
Anyway, has this happened to anybody else before?
