I have had mctd for 4 years and my body temp is normal...98.6 or a little lower. Blood pressure is high normal due to taking prednisone for 4 years. Don't think either condition is normal for mctd but nothing else is normal for it. Every case is different.
My case was extreme and life threatening and my BP was low normal even though taking high doses of prednisone. After 10 months prednisone caused my BP to skyrocket but meds have brought it down again.
