I was diagnosed with Lyme disease in june of 2012. I had an antibiotic treatment and now I've noticed arthritic symptoms. Can I still have the disease?

Yes. So-called Post-treatment Lyme disease is controversial. Some say germ is gone and disease is "autoimmune" residual. Others say the germ persists and can cause varied symptoms due to direct toxins or immune response generating collateral tissue injury and symptoms. Recent science suggests the causative spirochete has ways to persist in biofilms, spore-like round bodies and within cells.

Lyme disease. It is possible that you are still infected or have been reinfected. Certainly, post=lyme joint-pain is not unknown. Even after the infection is controlled, there are sometimes sequallae that remain. You may need to see an infectious disease specialist, who is the expert in detecting and then treating some of the more difficult maladies.
