That feeling is very miserable - I've been there. One thing I suggest is focusing on your playing posture. Do you stand or sit? If you sit try standing, make sure to keep your shoulder blades back and down, don't hunch over the guitar - I for years did this and I ended up pinching my cubital nerve causing the electro shock feeling in my fingers. I know this may sound counter intuitive, but when looking at the fretboard, look at the dots on the top of the neck - not faces. This helps you put less strain on the neck. I hope this helps!
