Hello Shanibelle,
What your husband is experiencing is called Paraesthesia (abnormal sensations, sensory symptoms).
I wear socks most of the time due to pain from the coolness of the floor. I prefer carpet over other types of flooring for this reason. Cold water can cause pain for me.
It's also possible to experience pain from clothing, bedding, a light touch or anything that may 'touch' him...hopefully he will not experience this but wanted to let you know it's possible.
Note: my response is based on a diagnosis of MS
