Adhesions, ectopic pregnancy, pelvic infection

I had an ectopic pregnancy (tubal) which was diagnosed early, in the 4th week of pregnancy. the doctors terminated the pregnancy by using the drug methotrexate injection (single shot) after they could not see the embryo in the uterus even when the hcg level rised beyong 1000mg/ml. after about 1-2 months i started experiencing severe lower abdominal pain and discomfort around the ovary area. In the following ultrasound scan the doctors said, that it looks like fluid collection in the left fallopian tube (where the ectopic pregnancy was). due to severe pain, doctors came to a conclusion that they have to remove the fallopian tube. so i agreed and underwent a laparoscopic surgery ( a week ago), but doctors found that i actually have adhesions covering the ovary and fallopian tube and also some fluid collection. they said they have removed only the adhesions and did not remove the fallopian tube. they concluded that, these adhesions might have come as a result of the tissue damage during the ectopic pregnancy and also probably due to some silent infection. I never experienced any infections not even UTI in my life or may be was not really watching myself properly..!!..and i was shocked when doctors said it could be because of some silent infection. also no infections were found in any of the blood tests or urine tests. i was considered as hemodynamically very stable. but, as you know adhesions come again. i already started having severe pulling pain again in the same ovary area and the pain extens to my thigh, the same way as before. I also have shoulder pain ..doctor said I will have this shouler pain bcoz of adhesions !
Kidnly help me suggesting some medicines for my condition..I want to be relieved of pain and also prbably prevent any more adhesion formation..!
