For years I have experience terrible waist pain,it either starts from my left or right side.it starts as a sesention,as the pain goes around my entire waist line,that is from either side to my navel line,going entirely round my back,it then grips me and becomes very very painful.this pain sometimes last up to 5minutes or more.I experience the pain once in a month at times,sometimes twice or more,sometimes I don't feel the pain for two to three months.I have seen a gyneacologist and was treated for PID but the pain persisted,I have also been treated for ulcer but the pain continues,I have also seen an orthopedic doctor but was told its not a bone problem.what do I do I was 14years when this pain started and haven't started having sex,now am 28years.*** am troubled what is wrong with me.
