It is more than likely a stress rash mnaha.
My Partner gets them a lot, yes, he is a sufferer too!
I think if you are both exhausted and have arrived in a reasonably 'safe place', it is a good idea to rest up and re-energise and after all, it is part of your adventure.
Don't feel pressurised. You will know when you are ready to move on.
Your Wife will be feeling your pressure and stress. After all, you are in this together.
This is a major thing you are both doing here and with the long journey as well, you will feel very tired and a bit under the weather in the process. It's not just your trip, there was everything else you had to do before you left and the, emotions that go with it.
I am actually quite excited for you. I just have a feeling that once you do get to your destination, that you will feel so different and it will give you a new lease of life.
The dizziness will be your exhaustion, it will pass.
Isn't it amazing how we can feel so bad and frightened when we are just pottering around our homes and here you are travelling thousands of miles!!
We have this amazing skill in survival and finding those coping skills to get to safety and deal with anything we have to, which is what you are doing now.
I remember when we moved last time, after we had packed, we were so exhausted that we could hardly hold up our bodies to eat a meal and we both looked at each other and agreed that we stay the night before leaving and get a good night's sleep.
Sleep can do wonders for your wellbeing, even a little snooze during the day.
The headache will be the pressure from the stress and I have that tender to touch feeling from time to time. It will pass after a few good meals and plenty of rest, but don't keep prodding and feeling it as my partner does, try a cold compress and leave it on for a few minutes and if you are up to it, maybe a walk around the town will help.
