Dear Afaq, This is nothing but just a type of anxiety you develop when being in a crowd and the headache is the bodily outcome of this anxiety. Chances of your overcoming this malady is high when you expose yourself consciously and frequently to such situations and people. Also, you need to do some homework along with. A change in your lifestyle, i.e. taking up an exercise regime followed by relaxation technique in which you relax your body by taking deeper and deeper breath (Inhale and exhale). When you find yourself fully relaxed by the deeper breath, just bring the anxiety provoking situations to your mind and try to see each and every aspect you feel nervous or anxious. When you continue this exercise and your frequent and conscious exposure to the anxiety provoking situations can effectively help you become alright. Continue the relaxation technique and bringing the situations to mind twice or thrice a day even if you don t go for physical exercise. However, it is always better to club it for a positive change in keeping your mind and body hale and hearty. Get well soon, Dr Rajesh Thottingal Kalam Rehabilitation Psychologist from India
