Debdeb, I've had dermatomyositis with ILD for over 13 years. There is no cure but it can be managed. The biopsy does hurt I won't lie, but it will give the doctor more information. I see a rhumatologist and a pulmonary doc. They are very helpful. There is a Myositis Association on the net that gives a lot of info for us. Also you can request books from them that you can give to your doctor. They also have a convention once a year that gives you a lot of info. They have people from all over, doctors from all over and care giver classes for your caregiver. Do not give up, one day at a time, enjoy life and pray constantly. I hope this helps.
