Since it has been a few months I would recommend you consult your physician about this.
Hi Aubrey, I have a costant tingling all over the body. So I have read alot about tingling and stuff related, I would think that you don´t have to worry. Because if your hair was pulled, then probably that have hurt some nerves that just need a time to heal. It can take awhile for nerves to get better. But if you think it is getting worse after awhile then you should ofcourse get it checked out. But ofcourse I´m no doctor so this is just my opinion. Good luck, I hope you get better soon :).
My best,
Dagun
