my daughter is almost 12, normal height & weight. today I picked her up from school (6th grade) for a stomachache & general poor feeling. I have noticed lately that her armpits are swollen again. She says they are commonly tender. there is no redness of the skin & no fever, nor recent accident. since infancy she has on again, off again had swollen armpits & stomacheaches, as well as purple circles often under her eyes (apparantly hereditary on her father s side). she has always had difficulty getting to sleep. I have asked her Doctor over the years at well child checks if I need to be concerned, investigate further, etc. but as she is normally healthy otherwise, the Doctor responded she did not see a need. I am wondering if she has food sensitivities. what do you suggest?
