Hi, I am currently in Nepal. For the past five days I have been experiencing headaches, some nausea, stomach ache (all on and off) and have found white stringy floaties in my urine. I am also easily exhausted during this time. No diarrhea though. Eating plain food and drinking nothing but bottled water but it doesn't seem to fix the problem. Is it likely to be a stomach bug? I can buy antibiotics over the counter here, such as Ciprofloxacin. Not sure whether they will help though.
