Welcome to HCM
We understand your concerns
You may not be correct. Nerve
problems arise when they are agitated. There are nerve fibres everywhere throughout your body.
Secondly psychological nervousness
can also cause symptoms as you mentioned. You might be fearing smoking
cigarettes because it might cause you heart problems. Chest pain
the centre of your chest and tingling
explains that. Also because you are exercising regularly, any chest problems should come out during your exercise. Believe your doctors.
Stop smoking if you are not comfortable with it. Find a psychologist
for counseling. I can help you if you desire so. Get well soon.
