Could Stress Cause a Bald Spot on the Side of My Head?

I am a 45 year old male and have had a bald spot on the right hand side of my head for about 4 weeks. There is no itching or discomfort, and its about the size of a 50p piece. I am a smoker and probably drink more than I should, my job is also quite stressful.

could you give me any advice please? thanks.

I cannot diagnose a bald spot without seeing you. In addition to stress, there could be many causes, such as a fungal infection, alopecia areata, etc…

I recommend that you see a dermatologist to diagnose the scalp condition you have.
