i have like a "bulge" on my lower back, just on the right side and it felt like fluid under the skin, i was laying in bed and i think it "leaked" and in the end i squeezed it and it was clear fluid, not gooey but a little thicker than water, now on my back it feels like there's a slight indent and a small scab where the opening was, a little worried as i'm 17 years old and shy, i don't want to see a doctor unless it's serious, but if it's overly serious i think i'd rather not know as it would be scary.
i can try and answer any other questions.
