Hi,

I've been having this weird thing that I discovered around 6 years ago... It feels as tingling, tickling electric kind of sensation running down from the top of my head all the way to mid upper back (approximately where my bra line is) on my right side. It begun when I put loud music from my phone's speaker very close to my right ear and the ''electric'' sensation just begun running down my body. I'm curious if I possibly could've sustained some spinal injury since when I'm not triggered I still feel very sensitive on my right side of my upper back. My left side is normal feeling. I've had some level of injury once before this sensation issue begun and I just wonder if I could be having just odd post-trauma issue from the injury (I never went to doctor due to financial status)..

Thanks.
