Good day i have been unwell for 3 months, was hospitalised and eventually diagnosed with inappropriate sinus tachycardia. i am still unwell, weak, have tingling and numbness, head aches, pain in my neck,throat and body. heart palpitations?

Second opinion: I recommend seeking a second opinion from a specialist in internal medicine or in infectious diseases who will take a thorough history and system review, perform a complete physical examination and order appropriate tests. Inappropriate sinus tachycardia is nonspecific. You may be referred to a neurologist. If no overt pathology is determined, you may be helped with stress management therapy.
