Your story reminds me of my neighbor. He thought he had simply slept in a weird position, but within a few days he noticed weakness in one arm and kept dropping things. The neck pain was bad enough, but the tingling and reduced grip strength were what finally convinced him to get checked out. While helping him research, I found trapped nerve in neck symptoms and relief options useful because it explains common symptoms of a pinched nerve in the neck and when they might need medical attention. The weakness you're describing would definitely make me take it seriously rather than just stretching through it.
