It's funny you mentioned camp because the first thing I thought of was a bite of some sort. I don't know where you are from or what diseases are there, and I don't know the symptoms of Lyme Disease or Rocky Mtn. tick fever, but I would certainly mention that your son got sick right after going to camp in the woods.
Maybe someone on this forum that knows about these diseases and their symptoms can give you more detail, but I certainly think it's a factor in your sons illness.
Sounds like H1N1, Strep (which can cause rash and muscle aches) or good, olf fashioned Lyme Disease.
Go to the ER- strip him down and have every millimeter examined for ticks or the bulls-eye rash (including hair, inner ears, buttocks, etc.)
Doxycycline-class antibiotics can stave off autoimmune problems pretty well in Lyme Disease if treatment is started quickly.
Don't pass GO- take hom to the ER or to an urgent care clinic- or to the Doc in the am---you have time to prevent disaster-
Praying for him (and you)- and know he will be well and bounce right back xoxoxo
Welcome to the MedHelp forum!
It is important that blood tests are run and typhoid, measles, Dengue fever, viral hemorrhagic fevers are ruled out. It could also be Lyme’s disease. Hence it is important to get complete blood count, urine examination, test for typhoid, dengue and Lyme’s. Please take your son to a pediatrician or ER ASAP for these tests.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
