I am having pelvic pain in my lower abdomen I am a female 42 years oldI am NOT in the best of shape. last night I had to lift is very heavy chair up and over very quickly but I did not feel any lower abdomen pain. this morning I felt fine and had intercourse with my husband and did not experience any pain. however later in the afternoon when we had intercourse again I felt a sharp pain and about 10 minutes afterwards felt cramping. as the hours have progressed into the evening my lower abdomen is swollen tender to the touch and it feels like my menstrual cycle is trying to start although I am NOT do for several weeks. I feel very uncomfortable crampy and just want to curl up like when I have my cycle. I am concerned that it is either a hernia of some kind or something else from the sexual intercourse. my husband is not large and we have not had intercourse frequently due to various sresses in our life even though our marriage is very strong. the main difference is that I finally experienced an orgasm which has not happened in several years it was after this the pain started. should I be concerned will it go away or could it be a hernia? the only pain I have is in my lower abdomen and its crampy feeling which makes it hard to move around. thank you for taking my question seriously.
