confused ....please helppppp

hello, i am 23 and need your advices. a year ago i started to have left breast pain and noticed my nipple had retracted but had no lump;i went to see my doctor who sent me for an ultrasound which came back normal and was given evening primrose oil.2 weeks later the pain seemed to go away and the nipple will retract and come back out at times.but again 3 months later  the pain came back and the nipple seemed to retract more often;went back to my doctor and had another ultrasound that came normal ,the dr said it could be fat necrosis as i had lost weight.the pain will come and go and my nipple was still retracted,a month later my breast started feeling heavy ,the pain was rare (nipple still retracted) with little back pain just behind my breast,very worried of the continous symptoms ,i did another ultrasound yesterday which again was normal(no lump,no lesion,no evidence of fibrosis or cysts)…i am lost and  confused as my  breast feels weird and my nipple is still retracted ;has anyone had same symptoms ???please help,advices…
