I'm sorry you still don't have any answers. Maybe your Gastro doc will help you get some answers since he likes challenges.
I hope your appt with the Cardio goes well. Hopefully, you won't have any problems with your heart.
I see that you have asthma and COPD. I was dx'd with Asthma a few yrs after being dx'd with lupus. Lupus also attacked my lungs a couple of yrs ago. Since you do have problems already, I hope your doctors are keeping a close watch on your lungs. I get x-rays every 6 months to keep check.
I really don't know about the spots, sorry. I posted a link in another topic on discoid lesions, but can't remember which tread it was. I will find it and paste it here for you too look at.
Take care and keep us updated. You will be in my thoughts and prayers.
Well, I thought I had posted a link about discoid lupus, but apparently I didn't. I know I was looking at the pics yesterday. Sorry about that!
