Some diseases and injuries could complicate your situation greatly. Here you have some stuff what can be useful on your trip:
- a package with antibiotics
- something for a sore throat and cough reduction
- a pressure bandage and gauze in case of an open fracture
- plasters for blisters
- stronger analgesis (painkillers, for ex. Zaldiar)
- Brufen and something strong for a diarrhea
Flying won´t improve your health. So take care…
