Re: Experiencing the following symptoms dizziness, left chest numb/pain, tingling sensation in my left arm and left chest, feeling of my heart beating near my left armpit.

Yesterday I felt numbness in my lower left arm, and tingling feeling(the same feeling you get when you sit your legs crossed and they fall asleep) in my left arm fingers.
I have had this left side neck strain pain for years, most likely due to my bad posture, being in a hunched position, and carrying heavy backpack.
I'm worried if either my heart murmur is causing this, or my arteries/veins due to possibly being clogged.
I have thought of undergo either intravenous chelation therapy, hydrogen peroxide therapy, and Live Cell therapy if it happens to be my heart murmur in order to get rid or my heart murmur and have a normal functioning heart.
Today I went to this store in which it sells organic stuff "Sprouts" to buy both Magnesium, and Niacin.I bought the band name "Country Life" Chelated Magnesium.Now the question is would taking 250 MG of Magnesium be enough to stop my left chest numbness, heart beat feeling, chest pain, back pain, knee/joint pain, tingling feeling in my hands, feet, and left arm?
