What Causes Scalp Folliculitis And Itching Sensation On Hands And Feet?

I have been on cipralex for a few years. Starting at 5mg then 10mg and the20mg. I took well to all the increases and was feeling well mose of the time however of the years there was som eweight can so I discussed with my dr that I am reducing the meds and fianaly reached down to 10mg after a 4 month weaning process.I knew I had to do it slow. I have dysthimia and I was very causes of sideeffects of reducing. I am seeing my dr tomorrow, but one thing in the last month it that the palms of my hands and feet are itchy and the I a developed a small area of scalp folliculitis. I do have an under active thyroid gut that is and has been made stable for many years Any thought. Thank you
