Swollen Pelvic Lymph Nodes?!
Question: Swollen Pelvic Lymph Nodes?
Answers:
Swollen lymph nodes tell us that some sort of inflammation or infection is going on in the distribution to where those lymph nodes drain. They are not swollen due to your position sleeping.
Unfortunately they are very non-specific so swollen pelvic (or inguinal) lymph nodes will infer infection or inflammation in the areas of the genitals (i.e. could be STD), buttocks, anus, lower abdominal wall and the entire leg on that side.
Who knows what's causing it. If you google it you'll find all sorts of scary stuff like HIV (which is a cause - like thousands of other causes).
But I think you diagnosed yourself with some bug bites. That could cause it.
