Hi, over the last 6 months I have had a bug or infection every 2 weeks, My immune system seems to be low, I be also had lots of stomach upsets - sickness and diahrea, which come on very quickly, I also have severe headaches, which hurt the right side of my head and face / eye. I had blood tests the start of last year for extreme fatigue and headaches, which came back negative to everything so no further tests were required. Thank you
