I've been suffering from pectoralis/shoulder pain for 1.5 years now that the doctors couldn't seem to diagnose, and I discovered by accident that megadosing on the Jarrow B12 took my pain away COMPLETELY. It's very confusing - I don't know if that means the pain is being CAUSED by a B12 deficiency or what's going on. But because it made me feel basically 100% better, I'm desperate to continue with it! Alas, I have to breathe, and Jarrow's B12 made me feel like I was honestly suffocating at times.

CrimeofPassion...I was b12 deficient, discovered about 20 10 years too late, unfortunatlely, and started the subligual liquid Pure Encapsulations 2 yrs ago. I also have Psoriatic arthritis. My neck had been in unrelenting level 10 pain for 4 yrs. With the first 2500mcg of methly-b, my neck pain went to a level 4. The next day it was gone. In that month of higher doses of b12, I accomplished a year's worth of worth. I had barely been able to move for quite sometime.
Along with the unexspected pain relief and ability to move better, I also immediately began coughing. In that month I also experienced extremely unusual side effects to the methyl-b. I saw specialists for each and was told this was thier assumption. My doseage was cut in half, then half, again. I was tested for a year to try to discover the cause other than the b12. I had to reduce my doseage to 250mcg per day, barely enough to keep me thinking straight. When I take more I experience the breathing problems, skipped heart beats and irrational rage. I try to keep as close to a small dose.
So, you're not the only one experiencing adverse side effects, but you're one of very few, I'd suspect. Welcome to the herd, zebra friend.
