My question would be have you gone to a doctor??
See your Chiropractor for an adjustment before you travel. It really works!
If you are not seeing a Chiropractor - see one now. They not only can make back pain go away, but they are whole health practioners. See one that is into Functional Medicine. I do and I am so very happy - and pain free, plus he is working on my stress and anxiety! Finally a doctor that not only can help - he cares!
