Hip pain relieved by B12 shot?

Hi,
As well as having a high ANA with great fatigue, I had developed a very painful hip joint/tendon primarily on the left side. It was determined to be hip flexor tendonitis and trochanor bursitis by orthopedic evaluator, and physical therapy has been prescribed.
Although my blood work doesn't indicate a B12 issue, my dr. has it set up so I can periodically get a B12 shot for fatigue. I hadn't had one for about 6 months or more as I hadn't noticed a huge difference the last few times I had had it done. However, I decided to have one the other day since I have, so far, unexplainable fatigue.
My ANA came back posative at 1:1280, but sed rate and other specific autoimmune tests are normal at this point. With all this in mind, is there any reason anyone knows of that after I had that B12 shot (the very next day) my hip pain decreased about 75%?
I will of course bring it up to my doc at my next appointment, but am just curiouse if there is anything I should inquire to have looked into regarding this.
Thanks so much for any input!

Hi
Thanks for keeping me posted!
If the B12 is bound to blood it is stored in liver in that bound form only. Then it is released in bile into the small intestine. The B12 we take orally is absorbed by the mucosa under the tongue and by small intestine. From the small intestine, it is bound to intrinsic factor (IF) and then absorbed into the blood. Absence of IF can cause no absorption of B12 from intestine. However by injection it reaches directly into the blood stream and absorbed by the cells.

Absence of IF is also known as pernicious anemia. Is your hemoglobin and red blood cell count low?

Please let me know if there is any thing else and do keep me posted. Take care!

Hi,
Thanks for the responce. Is there any condition you know of in which B12 is in the bloodstream, but the body does not utilize it properly? Perhaps whatever process brings it from the blood to the cells is comprimised?
Thanks!

Hi
Thanks for writing to the forum!

I have an article which may interest you : http://ezinearticles.com/?Vitamin-B12-Shots-For-Chronic-Fatigue-Syndrome&id=656334

B12 deficiency is several times misdiagnosed. It would be helpful to repeat the test to know actual B12 levels in the serum.

It is difficult to comment beyond this at this stage. Please let me know if there is any thing else and do keep me posted. Take care!
