So I recently went to a summer camp in Tennessee and I was in two bodies of water, a still and relatively cold river (which I think I got a little bit of water up my nose), and a whitewater rapid that was still relatively cold but a bit warmer than the former (in which I got a LOT of water up my nose due to my groups' raft overturning near the end). I swam in the stillwater river 5 days ago and went rafting 3 days ago.

Now I'm extremely scared that I might've contracted the deadly brain eating amoeba infection, especially from whitewater rafting, since the water was warmer and I really got a ton of water in my nose. According to some googling I did, an 18-year-old girl died the exact same way back in 2016, due to her raft overturning, which just makes me even more worried. 

I've been monitoring my symptoms, perhaps a bit too compulsively, for the past 4-5 days. Since then I've been noticing some unusual symptoms like a mild headache that comes and goes, mild fatigue, and most notably a pretty stiff neck, all of which are early symptoms of the brain eating amoeba. Sometimes I've felt feverish too, but my temperature is apparently normal at 98 degrees. I haven't had any serious symptoms like vomiting, loss of smell/taste, photophobia, or seizures though, but I'm really worried that they might suddenly develop in the next few days.

So guys, what should I do to manage the next several days and to reassure myself of this (most likely) anxiety? I know that this disease is extremely rare but I still get very worried especially when I have symptoms associated with it. Do you recommend me to go to the doctor and get checked just in case?
