mixed connective tissue disease, symptoms?

my pcp just told me i have possible mctd, does anyone
else experience soft tissue swelling? i have salivary
and lymph node swelling,swelling in my arms
(elbows)i also have pain with the swelling, it is chronic
never goes away-fatigue, low grade fevers,joint pain,
are some other symptoms-my blood tstes have all been
normal-i'm not convinced that i have mctd-need some
opinions and ideas on this-thanks
