Hi. If anyone has read my previous posts, you will remember that I have been feeling ill for about eight months, with symptoms including tiredness, aching muscles/joints, hair loss and itchy skin. I have had blood tests which people commenting on here seemed to think needed further investigation, but my doctor seemed to think were ok. I returned to my doctor and requested further tests for B12, folates etc and I had these done on Friday. Over the last few days though, I have felt a bit better. I don't think my aches and pains are as bad and I am not itching all day. I am worried now that I have pushed for something that I shouldn't have done. Is it common for symptoms to come and go or have I made myself feel worse by imagining the cause?
