abdominal pain, nausea and fever for 8 weeks.

Type your medical question hereOur daughter age 44 has had ME/CFS for over 20 years and is on a dairy and gluten free diet. Her daughter, age 7, is on the same diet. Over the last  8 weeks , starting within 3 days of each other, both have continued to complain of nausea, abdominal discomfort and bloating with a low grade fever of over 99F. Her daughter frequently wakes at night with "tummy prickles" and nausea. Both have been seen by the GP but without any resolution as yet. Your advices would be very welcomed.
