Hello and welcome to Healthcare Magic. Thanks for your query.
The symptoms which you have described are likely to be due to anxiety
. Palpitations, light-headedness, panic attacks, strange sensations like pins and needles, etc. are symptoms that are commonly seen in anxiety disorders. Drugs like cocaine are well known to cause a variety of psychiatric problems, including anxiety / panic disorders.
I would advise you to 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 these symptoms.
Wish you all the best.
Dr. Sheeba Stephen
