Hi Yasmin. I want to first say I wish your sister a speedy recovery. Secondly, the very same thing happened to my daughter when she was 14, her left ovary was removed as it was twisted and started to go gangrene....only after she was diagnosed with constipation and sent home by one hospital.....Also, the other hospital thought she might have peritonitis, they opened her up on her right side (even tho the pain was on her left) and then proceeded to cut her all the way across to the other side. Her lungs collapsed and she was in intensive care for 48 hours.......her dad and I took turns to sleep by her bedside as she was in a side room...so I will never forget New Years night 2000.....!!! But the upside is, she is now expecting her first child late August, after thinking it may be hard to concieve...it took her 2 months!!! I'm concerned that LT has affected her kidneys as I need mine to be 100% healthy.
