Hi my name is Ernie, im 27 year old male. Been dealing with alot of issues for six months consisting of heart palps , irregular rythem, dizzy/lightheadness not vertigo, change in bowels. My doc says its all anxeity related. Recently I found out I have vericocele no pain though. My blood work shows total Testosterone at 392 and B12 at 315. My doc put me on 2000mcg of B12 for a month but after 2 weeks i noticed i get pain in left arm and tingly fingers in left hand so i stopped taking the B12 pill and it went away, does this show B12 causing me a blood clot? Tommorow morning i go get my total t tested again and the free t also b12 tested again to see if there has been improvement. Sorry for the paragraph i appreciate your time.

### output:

Ernie, the B12 is probably a red herring. It probably didn't cause the problem you started with or the arm sensations. When you have the constellation of things that are bothering you, it is reasonable to look for a systemic problem. It sounds as though your doctor has done that and not really found a culprit. Often, the problem is not an illness but a lack of some of the things that we all need to stay healthy. Specifically ask yourself and of your doctor about, Exercise: Exercising every day for 20 minutes should be your goal. Is your body weight excessive. A little can go a long way if it is mostly in your belly where it affects sleep, joints, heart rhythm and when you're older, diabetes and heart disease. Abnormal sleep. Sleep disturbance is often present in people who are overweight, particularly those who snore. If you are very tired in the morning, sleep easily during the day and snore loudly, you may have sleep apnea. It is a common cause of abnormal heart rhythm requiring treatment.
