I'd say overreacting. Your "genius" husband was just doing the only logical thing by putting a bag over it.
It still got wet. It happens. Try to dry it out... If it does not work and you have weeks to go before it's removed, go to the dr to get it recast .
Thanks for your help. It was damp by his hand and a little bit at the top above his elbow. I used a blow dryer on it and it seemed to have dried up pretty well. It could have been a lot worse. I think it was just me over-reacting.
Thanks again.
Hello!
As it is damp inside as water might have entered and the cotton and the material will soak water and there is every chance that it will not dry and a possibility of an infection it is always good to take him to the orthopedician for removing and recasting.
It all depends on what portion of it is wet? Get him checked.
If it is a minor portion and it can dry using a hand drier it is fine.
Take care!
