Hi- just seeing this post. I too developed the same exact rash after sun exposure on right and left thighs/upper legs. Looked just like King1234 photo.about
1 month prior to rash had elevated pancreas enzymes. Have been suffering from severe muscle pain under arms, upper back and shoulders for nearly two years. I have Raynauds, positive RNP (1.1) and have had both a moderately positive and negative ANA. Visited several rheumies and still searching for answers.
SLE '05, Sjogrens, fibro, Raynaud's, major depressive disorder, CNS problems, diastolic heart failure, GERD, 1st stage kidney disease. Many meds: better living through chemistry
