I am 30 and have just recently had some bloodwork come back and it showed that protein were high, but then got normal, but I had a positive ANA and high smith antibodies. They were only 1.1 I dont know if that is REAL HIGH OR NOT... I have a appt with a rheumatologist to hopefully get more answers. The only symptoms I have had are chest pain for 10 years knee pain for about a year my mri was normal). and I extremely sharp pains in my shoulder that last maybe 10 sec that has been off and on for a good while also.Nothing has impaired my daily activities. I just wonder what could be the underlying issue and if this is the beginning of something bad. Thanks!!
