Thanks for your query.Base on the facts and USG report that you have posted it appears that you have Ovarian cyst
on left side with congenital Divericulum of the Urinary Bladder
and Bulky Uterus
Your pain in lower abdomen is most likely to be due to Lt ovarian Follicular cyst
The bulky uterus has no significance as endometrium is normal
The Urinary Du\iverticulum does not need any treatment at present but may need in future if you get repeated episodes of UTI
.Please consult any Gynaecologist for treatment of Lt Ovarian Cyst.In the mean while you can take sinple pain killer like Brufen
400 mg twice daily which is available over the counter.
