Is your husband doing anything physical such as exercise or maybe his work is strenious,i am thinking maybe a pinched nerve or a trapped nerve,also migraines can affect you like this,as can being anxious escpecially when you are stressed about things because we tense up more and makes the joints and muscles hurt more.
stress does not make you lose sensation. it more attacks the heart, and the brain, and throw you into anxiety..
tands, I need to know how old is your husband.
My husband is 42 yrs. old
I suggest your husband should see a Neurosurgeon and have an MRI
Full of questions but no answers,i can tell you from a patients point of view that anxiety can make you feel numb.
