Thank you for posting your question here, I will try to answer it to the best of my abilities.
It doesnt necessarily mean that it is a cyst
, it could be appendicitis
for all we know. But we will need to run some tests to narrow done the cause, as many things can cause pain in the right lower side of your abdomen.
UTI (urinary tract infection
problems in your intestine
inflammatory disease in your ovaries, etc
The list is pretty long, so I recommend you see a doctor, let him run some tests like full blood test
, urine test and maybe an ultrasound
as well to find the cause, once that is found we can start treating you.
I hope this answered your question.
