Hi, Welcome to Health care magic forum.
As you describe the problem in the brain wont look like this. It may be due to some
contractures of the muscles of the neck.
I advise you to consult a physiotherapist, for diagnosis and treatment. With few stretches and massages you will become allright.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to develop blood, general health and resistance.
To avoid unwanted pains avoid taking potato, other tubers, tomato, egg, chicken, and sea foods.
Wishing for a quick and complete recovery. thank you.
