Hello and welcome to Healthcare Magic. Thanks for your query.
It is important to understand that anxiety
can manifest itself with not only psychological symptoms, but with physical symptoms also. It has been found that anxiety disorders are associated with certain neuro-chemical imbalance in the brain and this can cause the person's sensory threshold to get lowered and he / she can become 'hypersensitive' to sensory stimuli, and therefore have a variety of strange symptoms. The underlying anxiety also causes a person to become more worried about these symptoms and soon this worry / anxiety itself then starts worsening the symptoms more.
Since this problem seems to be causing you a lot of distress and affecting your school performance also, I would advise you consult a psychiatrist
for a detailed psychological assessment and further treatment. There are effective treatment options - in the form of medication or counselling
which will help you overcome your anxiety and its related problems.
Wish you all the best.
Dr. Jonas Sundarakumar
