Itching tingling face nose and ears

Hi, let me introduce myself… I’m Pierpaolo and I’m an Italian guy who’s actually using Google Translate :rofl: I haven’t been diagnosed with MS but I wanted to tell you and ask for advice on the symptoms I’m having and they’re destroying me. I am a 25 year old boy who has been suffering from fibromyalgia since he was 16, diagnosed at 19, I have had many symptoms including pain, chronic fatigue, memory problems, severe anxiety etc. it was very difficult to live with all this and in reality I was also able to manage the situation well by changing my lifestyle, diet and changing my thoughts, I was finally seeing the light at the end of the tunnel, but about 3 and a half years ago due to an injury in both feet after a period of pain my feet started to tingle and initially my brain went crazy making me very anxious. the itching lasted about 4 months and one night while I was in bed trying to sleep my face started tingling, and from there the life I was trying to build, the person I was began to destroy itself, I live with this itching/tingling on the face (also in the ears and nose) for about 3 years, it’s exhausting, and is sending me to the mental hospital, I’ve had several visits and tests… brain MRI, thyroid ultrasound, chest x-ray, allergy tests (I was allergic to dust) the final diagnosis was anxiety-induced itching, so after a bit of indecision I tried various psychiatric treatments with different pharmacological therapies but nothing at all. I’m in pieces. I wanted to ask you, do you think it could be undiagnosed MS? Do any of you have or have had similar symptoms?
can anxiety create these continuous and chronic symptoms? If anyone has any idea what this might be about, I have some thoughts on the matter, write to me, thank you and sorry for invading your forum
