Hair pulling sensation 2 years after transplant - what could be causing this and what are my treatment options?

I had a hair transplant in 2021 . Since about 6 months ago, I've been experiencing strange sensations in my scalp, similar to the feeling when hair is pulled. The symptoms evolved over time, starting with a burning sensation, then itchiness, and finally the hair-pulling feeling described above. This sensation can change, but it is generally a 24/7 feeling, impacting the quality of my life. I am in desperate need of help I visited a dermatologist with no luck
