That does sound very difficult to have electric shock-type sensations in your shoulder and now your scalp, in addition to the pain with swallowing and the horrendous itch near your shoulder.

It sounds like the electric shock itch/tingle of your right shoulder finally went away? If so, was there a treatment you were given for this, or what do you think made this sensation go away?

@loulou123 Has anyone examined your spine for possible issues? Electric shock pains are usually nerve compressions. If you have any disc or alignment problems in your neck, or possibly arthritis, it could produce symptoms like this. I had a spine problem in my neck and have had spine surgery. Before my surgery, I had itching and pain around my scapulae, pain in my ears, and muscle spasm headaches onto the back of my head from my spine problems. You might want to consult a neurologist and have a physical therapy evaluation with a PT who is familiar with rehabbing spine surgery patients. Nerves pass through some very small spaces in the body between muscles, around joints and bones, and misalignment can compress these spaces.
