Hope you have a wonderful trip, take lots of pictures :lol:
Like you, I hate to think that every little idiosyncrasy in my body is due to Lupus. However, whenever I bring it to my doctor's attention, it turns out that, in some way, it is!
Your jaw problems may be early signs of TMJ (I suffer with this also). TMJ is a symptoms of Fibromyalgia which is a co-existing disease with Lupus (fun huh?). Also, Lupus is an autoimmune disease that causes inflammation. As such, TMJ can be caused by Lupus.
TMJ (Temporomandibular joint) relates to the jaw joint. The TMJ connects the lower jaw (mandible) to the skull (temporal bone) in front of the ear. TMJ syndrome may cause ear pain, ringing in the ears (tinnitus), and hearing loss. Sometimes people mistake TMJ pain for an ear problem, such as an ear infection, when the ear is not the problem at all. Certain facial muscles control chewing. Problems in this area can cause head and neck pain, a jaw that is locked in position or difficult to open, problems biting or chewing, and popping sounds when you bite.
Perhaps you can discuss this possibility with your doctor when you return from your vacation. Until then...have a wonderful time! :P
Peace and Blessings
Look For The Good and Praise It!
