Hello. I am very suspicious that you have PID, pelvic Inflammatory Disease. You need to go to an urgent care or ER for IV antibiotics.
The lump may be a swollen lymph node, but either way you need to go to an ER. This can be serious and progress quickly into sepsis.
PID if often a chlamydial or gonorheal infection. But other common organisms can cause this. You will need antibiotics. Please be sure you follow up with someone soon regarding this. With an IUD, again this can be serious.
