First, go to a spinal consultant and get an MRI. This will either conform or eliminate a serious spinal problem. I was referred to physiotherapy who said I had a age related stenosis. I wasn't happy so got a referral to a consultant and found I had 3 prolapsed discs with my spinal column compressed to 3mm. (Actually 2mm in the end) I needed surgery. You are better off in the long run to find out the underlying issue early.
it's in Thai and the translations indicate 'population' and something else. Another copy of the id and the house book makes sense as that is what they want at the IO to prove address. Thanks for responding.
