I am new to this group despite following Thyroid UK comunity for a year or two now. I have been concerned over the last few years about the potential of thyroid issues due to nodules growing in both sides of my thyroid. Investigations last year found nodules were benign with normal TSH 0.9 (range 0.2-5.69) so I have tried to get on with life despite thyroid symptoms. I have had increasing symptoms of extreme tiredness, mental fatigue, forgetfulness, brain fog and low mood. In addition to this I have had oedema in my lower legs and upper arms, swollen tongue, some clumsiness by dropping or tripping and falling appetite. I felt that it was time to head back to the GP as symptoms were now impacting on my ability at work.
GP was very sympathetic and requested a raft of blood tests. She was even happy to request thyroid antibodies. To my surprise all have come back clear except B12 which is deficient 145 (range 120-1000). I knew nothing about B12 until this week but have been reading some posts here to better inform myself. There was another test done for intrinsic factor but that has come back negative although GP did say this was unreliable. He also said that the deficiency did not appear to have affected my red blood cells. I assume this means I don't have PA. I have been prescribed 5 injections over the next 2 weeks starting next Monday. I asked what happens then and GP said that I would be retested in 6 months.
Is there anything else I should be asking ? How do I know that the treatment has been successful if I am not retested till 6 months ? Can I really expect to feel better just with this short course of jabs ? Should I be having regular jabs after this initial dose? Should I be asking the GP to be ousing the cause - my digestion has been an ongoing issue with so say IBS for the last 10 years ?
Sorry lots of questions I have really been floored by this and realise I know so little.
Thanks in anticipation. Tanya
