I visited my GP in Nov last year complaining of extreme muscle pain in my arms & legs, itching and tiredness no gastric problems at all. After doing bloods he called me back to say really high LF results. He referred me to see a general medicine consultant who would look at both issues LF & muscle problems!!!!!! Whilst waiting for my appointment to come thru I had more bloods done at the GP surgery just for a healthy heart check. I was once again called back for LF abnormalities. I seen a different GP this time. She was so concerned about the liver function levels that she referred me to see a gastroenterologist on a urgent 2 week referral and couldn’t understand why the other GP had sent me to general medicine. She told me to forget about my muscles until I got my liver sorted out. I was diagnosed with PBC by gastro and put on URSO and questran. I also went to see the general medicine guy and he said he couldn’t understand why I had been sent to see him. So I think he felt sorry for me and said would run some vitamin test as a Vit D deficiency could be causing muscle pain. It turned out I do have a deficiency in Vit D and put on 20,000 iu 3 times a week for 7 weeks with a blood test to check my calcium levels after 4 weeks. I’ve now been taking the vit D for 4 weeks and since then have started to get bone pain in my fore arms,wrists, above elbows and above knees and swollen lumps on my wrist bone it’s almost like RSI. I’m wondering if this could be caused by the high dose of Vit D. I’m worried for my mobility and feel movement in my arms is getting limited. I also get very slow cramps in my arms and legs when I relax in bed. I had my bloods done today and waiting for results for the calcium levels. Sorry about the long message but I’m worried and wonder if anyone else had suffered with this.
