Hi and

to disABILITIES!
I would start of explaining some things to your husband, especially about your feet and that he does not really understand the situation.
Basically a person has a certain amount of energy available to them daily. If they relax during the day the amount of energy available wil increase; when they sleep at night they recharge their system,
However, when in pain energy is used up much faster than in normal conditions. If you become exhausted, with by what you have done or, more importantly, what you have done while in pain your system will not recharge to the original energy level overnight and you are starting the next day with a lower amount of energy available.
Please ask yourself the following questions. Here are the suggested answers to go with them.
1. Are you disabled (even temporarily)? Yes.
2. Do the people you are traveling with, such as your family, know you are disabled? Yes.
3. Do you expect to meet anyone you know during this trip who may not know you are disabled. Probably No!
4. Do you expect to meet a bunch of people who you will probably never meet again in your life? Probably yes!
5. Is there any reason at all that you should care what these people think about you? Absolutely No!!
6. Will using a wheelchair or
ECV make for a better vacation for you and your family? Absolutely YES!
