Thal minor and vitamin B 12

Friends i am beta thal minor and i hv been taking b12 injection every month else  my thal minor symptoms like fatigue restlessness and breathlessness increases.

Somebody has told me not to take this b12 injection as it can damage liver, is it correct ?

Post taking b 12 inj. My yellowishness goes away from skin and i feel normal and energetic. Elese without b 12 my thal minor symptom increases that i feel tired all the time and skin gets pale yello.

I am 33 but i look 22 / 23. May be thats cz m thal minor.

The warnings about B12 and the liver concern people who have liver disease and can't properly process B12. Normally, your body will regulate how much B12 is absorbed. If there is a diseased liver, this regulatory process may not work properly. Otherwise, there is no danger. The fact that you see less yellow in the eyes indicates you produce fewer defective RBC's when you B12 is addressed.

Thanks for the response.
