I have had several weird sensations on my skin over the years, which have all been caused by anxiety. Nerve pain, feeling like there were bugs crawling under my skin, feeling like my skin was on fire, feeling like my skin was wet, hot, cold... when in fact it wasn't. For me it's just another symptom of anxiety, and my doctor has never been concerned. Back when it first started happening in 2017 there were times the nerve pain was so bad that even wearing clothes was too painful. I saw a neurologist and had an MRI - all normal.
Lately I've been really anxious and have had many abnormal sensations. Told my doctor, he was not concerned, so I'm trying not to be either
And so should you! Stress and anxiety can cause many strange sensations, even when we're not feeling particularly anxious.
