Question Response to first B12 shot

Hi - I just had my first b12 shot yesterday afternoon, and noticed about 6 hours later my heart started to pound and has been since. My heart rate is slightly elevated, but it beats so hard. I am also having chest pain but no shortness of breath. These symptoms are very remnicent of those I have with anxiety attacks I was experiencing on a higher dose of Armour. I just decreased my Armour dose from 60mg to 45mg a week ago and noticed a big improvement with these symptoms. I wonder if what I am experiencing now might be from the b12? I took an ativan and it helped for several hours. I am not "normally" an anxious person, but since starting this thyroid treatment I have been having anxiety attacks. I am to self - administer shots once a week for a month, then re-evaluate. I will call my ND tomorrow with a report on how I'm feeling. What have other people experienced with their b12 treatment? How long before you've felt the effects, better or worse? As always, thank you for your time!

Re: Response to first B12 shot

I'm not sure what you are experiencing. I take B-12 once a month, and my problem is usually for the first 24 hours I feel more lightheaded than usual. I don't know why I feel that side effect either. Let us know what you find out.

Re: Response to first B12 shot

When I started my B12 injections, the first 2 made me have a really bad headache and I just felt anxious and awful! I lowered the dose but took it more often and after a week I was OK.
Maybe you should try 2 1/2 doses per week instead of 1 whole dose.

Re: Response to first B12 shot

I felt wonderful after my first dose. I don't really remember feeling anything but MORE tired. I have severe PA. Technically, I have Putnam-Dana Syndrome. (AKA- Subacute Degernation of the Spinal Cord Secondary to Pernicious Anemia) My doctor told me that it might make me tired, because my body was going to be working hard to 'repair' itself. I honestly, felt MORE tired for about the first month straight.

That has since subsided.

Oh, yeah, I also got the weird yellow poops. YUCKY, I know. Sorry. Didn't know if anyone else had that happen to them!!

I'm still trying to figure out what else is wrong with me. We really thought that the B-12 was going to take care of all my crazy, horrible symptoms/problems. Alas, it hasn't. I still can't swallow solid food and my vision is weird. I have tons of pain in my muscles, joints and tendons. I have super dry skin, hair and eyes. I still struggle with fatigue. I've been working out for the first time in years (I was too sick to work out) and all that's happened, is I've GAINED 30 pounds. (Yes, I'm watching what I eat, too.) I've also started taking diet pills and I find that they make me feel even colder (I'm constantly cold.) and I still haven't lost a pound!!
