Just been diagnosed...still waiting to find out if it's actual Lupus or Drug Induced as I'm currently taking Carbamazepine. But I'm just wondering...my main symptom is joint ache. So does that mean that the auto immune disease is attacking my joints? Or does that mean I have an auto immune disease that is affecting another part of my body and the joint ache is just a symptom? I don't understand! I've read lots about it but nothing seems to give a straight forward answer to this. Can anyone help? Thanks x
