I am feeling strain and stretch feeling round the right neck, and right side of fore head since two months. It goes sometimes but comes back.?

Hard to know. If you're not doing some job or exercise that causes you to move your head far to one side or keep it there for a long time or puts pressure on that side it is really hard to evaluate this from afar. Keep a diary on what you have been doing the day before it happens. Check for any lumps or tender spots, try gentle massage on them when the neck hurts, and apply a warm compress or Arnica. Namaste.
