My 7 year old son has had fever since 2 days along with sore throat. the fever spikes back up to 103 once motrin wears off. could it be streps?

See Pediatrician: Strep throat often presents with sore throat and fevers. A quick strep test can be done, even at many cvss. If bacterial cultures are negative and it is a virus (often viruses have higher temperature rises than bacterial infections), alternating Acetaminophen with Ibuprofen as prescribed by a pediatrician, cold compresses (keeping the fever low naturally), may help. Best of luck.

Possibly: Why don't you speak with your pediatrician or primary care doctor? If you have none i would still suggest having him evaluated in a urgent care center as antibiotics may be needed.

Possibly should see: A child with 102 that returns after meds for 2 days may have a serious illness that needs a professional it may be strep or another needs med if exam needs cult only a prof. Can tell 2-3 days is limit if nothing you have peace of mind.
