Your symptoms could be related to some amount of pelvic infection
, mild hormonal
imbalance or a pregnancy
secondary to failed tubal ligation
as seen rarely. Please see a specialist for a complete evaluation and a trans-vaginal sonogram. Please get an infection ruled out and also any possibility of pregnancy. Once done, you can just sit back and observe along with symptomatic treatment to see if the complaints recur, when they would need active treatment. Please take a healthy diet, adequate rest and relax.
