Hey Akash, I did have this symptom a few months ago. Nerve tingling / pain would not start instantly but after a few minutes. My understanding is that it could indicate nerve entrapment. The exact spot of the nerve entrapment could be one of the three spots mentioned in TOS or your cervical spine. To rule out a cervical spine issue, my physiatrist used an MRI to verify that the vertebrae in that are looked ok. Also, for me, pressing on the area near the collar bone (scalenes) would trigger some of this even while looking up.
