<s>[INST] I have been suffering with abdominal pain for about a week, I was admitted to hospital where they found a blood filled cyst on my right ovary. That has now gone but i am still having pain on my right side...The hospital have blood tested me to make sure that i didnt have infection in my appendix. I am now starting to get back pain on my left side. Also prior to this a water sample indicaated i had puss cells however this was not picked up on a following sample [/INST] HelloPreviously pain was on the right side due to blood filled ovarian cyst, that resolved (according to you). Now pain recurs but on both side (pain in back also on left side) . Such type of pain on both side may be due to these reasons, This includes.1 Poly Cystic Ovarian Disease (pod) . Once again get in ultrasound of both ovaries because recurrence is very common in ovarian cyst, particularly if proper treatment is not taken.2 The next reason of such pain may be due to renal calculus on both side or on one side. So get in ultrasound of both kidneys as well complete urinary tract system.3 The next reason such pain may be due to salpingitis (infection in fallopian tubes) Gynecological examination will rule out the disease. In my opinion consult a surgeon / gynecologist and get their opinion. Hope this information will helps. </s>
