<s>[INST] hello,last week i had a few twinges in my lower abdomen and when i sneezed it hurt.  then last fri i had intercourse with my fiance and it really hurt and shortly after i felt very faint and sick and was in a lot of pain.  the pain got slightly better after ibroprofen.  since then i have felt better but a little strange in my lower abdomen.  also i should come on my period towards the weekend and i always get very bad mood swings and very sore boobs but this time i dont.  what could it be?  thank you [/INST] Hi. Thanks for your query and understanding of the problems you have, The commonest cause of pain after intercourse with the sensation of fainting and all are :Ovarian problems like twisted cyst or recently enlarged cyst due to internal bleeding or infection in it. PID-Pelvic Inflammatory Disease. Salpingitis and so on. I would advise you the following:Urgent ultrasonography of the abdomen and the pelvis and trans-vaginal USG if facility is available. Gynecologists opinion and per-vaginal examination, this gives a lot of information and better than that of the USG and so. The treatment will depend upon the reports. </s>
