I would expect that they have checked all your vitamins and minerals. You’re mentioning some things my mother had where she had buzzing, and like her skin was crawling, and what she called waves would come over her and through her scalp and her skin. She nearly died. They found out that four or five vitamins were completely bottoming out (calcium, potassium, some B vitamin and 1 or 2 more) and then coming back up a bit and then going back down. She stayed on vitamin therapy daily for 18 years till she passed. I just thought I’d mention it.
