Dr. i am 36 year old male.last 3 years i am anxious that i may have some disease. it all started with having pain in head, so an Mri was done which was normal. later on i started having some chest pains intermittently. i always had a feeling that it is symptom of heart attack. got my complete health checkup but got nothing.i have undergone complete health check in 4 different places with more or less same findings. my lidid profile was somewhat deranged for that drs adviced some lifestyle changes. in last 2 year i have started taking alcohol on regular basis. now i feel i am addicted to the same. although i have tried to quit the same and abstained for about 1 month twice in last 2years. nowadays i have numbness and tingling in left side of body and i feel that it could be stroke. 2 years back i met a psychiatrist who prescribed me nexito 10 mg which i regularly consumed for 1 year. i am a smoker for last 15 years. kindly tell Do i really need a psychiatry consultation and if yes what could my diagnosis. all my symptoms are real like numbness,chest pain,weakness in leg, sweating especially at night
