My son has had recurring fever (102-103 for 4 or 5 days) since he was 8 months old and it happened every 29-30 days for the last 4 years!!!! he has NO OTHER SYMPTOMS!!!! nothing. he is almost 5 and stil there is no explaination. I did see a holistic doctor and he perscribed something called cytozine parotid which is essentially the saliva of animals. it came in the form of a pill and it it smelled like fruit. anyeay, I think it is a natura antibiotic. I really did stop the recurrence of the fevers for the last 3 months but now he seems to get a fever whenever he sleeps too late at night and when he is stressed or overtired. what can that be?? please if anyone as any imput, i would really appreciate it. by the way, we went to an allergist, an ENT, and a rhumatologist. nothing came of it. i would appreciate any imput.
