Hi there ~
I understand your concerns. I feel like you are having the tingly sensation due to a neuropathic condition. I believe there are reports of this happening after a traumatic injury
and sometimes surgery if a major nerve
has been cut or you were not psychologically prepared for the surgery. It is interesting that you used marijuana post surgery, and wonder what it did for the pain. I also think it was not the best idea as there are many medications available for neuropathic pain
and you need to be consulting a doctor for the same. I hope this helps.
Take care and have a lovely day!
