Suggest Cause And Remedy For Numbness And Tingling In The Face

Hi, my husband 44 has had a numbness/tingling in the right side of his face and sore head for the last week, he works different shift patterns and was working nights last week, he is finding it continually difficult to sleep during the day as he gets older, and his job at the moment is quite stressful. We purchased a new house 2 years ago and it has had a few problems, since we moved he seems to get more worked up about things. The house is in a rural location and is often a struggle to get to work during these snowy periods. Do you think anything of what I have said might be why he having this numbness/tingling
