Hi there
@isjoberg sorry I can't relate to this, however I personally think you should call your GP and get it checked out before you travel. I recently had tendonitis and it was quite painful but not painful enough to get too worried, I left it for 5 months and finally went to the docs who diagnosed it straight away and was treated with a steroid shot the next day and the pain went, I recommend that if you have a concern it's always best to get it checked quickly
