8 months after hair transplant. Issues. What is causing this?

I had my HT on 5/1/18 and 3 months after the procedure I started having this weird sensation on the recipient area only. On the right side it feels like needles and in the center of the head tingling burning sensation and it gets worst when I am driving, my HT surgeon said it will get better with the time and he his surprise that this is happening. I am going through neurologist and he is treating me with nerve medicine which is not helping much he also did MRI and it came out normal it didn’t show any nerve damaged. My GP thinks small nerves are hard to see in the MRI and he thinks those nerves were cut and they are not growing and that is causing all of this pain. this HT has made me handicap I am not able to do anything at all this moving sensation on the head is all the time. It’s scary it’s painful and it feels like my head is going to blow when I place my hand on the head it relaxes it or if I itch it relax I also saw dermatologist and she said skin is fine.please help if you know what is causing this.
