I am 20 years old, too young to be worrying about bodily issues. However, for the last 6+ months I have been struggling with intense lower right abdominal/back pain. The last few months I have lost my appetite and any interest in food. I have also had my period only 3 times in the last year where prior to which I had them regularly. Same time every month. Every day in the last month I have felt sick and fatigued. On my days off from work, I wake up in the morning and have no interest in getting out of bed. I find I don't have the strength to do so. When I do get up I get light headed and dizzy. I've also had problems with frequent urination and constipation. A few nights ago I was overwhelmed by a stabbing pain in my lower abdomen/ pelvic region. I went to the hospital and try ordered blood work, ct scans, and an ultrasound. Both CT and ultrasound came back negative, however my white blood cell count was 20% higher than it should have been. I was diagnosed with a bacterial infection without any answers to the fallowing problems I have experienced. I have lost hope in finding the source of the pain and relieving it. Should I seek another opinion? Do I have important things I should be worrying about? Please help!
