Thanks for posting your query,
Joint pains in young can be due to autoimmune diseases like rheumatoid arthritis
, gout, inflammatory diseases like SLE, bursitis, fibromyalgia
To pinpoint the diagnosis, complete physical examination and investigations like complete blood counts, ESR, RA factor, CRP, serum uric acid, serum creatinine
, X-ray and MRI joints from a rheumatologist are needed.
A high levels of anti- DNase is suggestive of an autoimmune disorder which needs disease modifying agents and oral steroids to take care of the symptoms. You need to consult a rheumatologist
for proper treatment.
I hope this information has been both informative and helpful
