Can Crystal Meth Cause Lupus?

just seen where someone asked if crystal meth use can cause lupus. My son did meth for one year and thank God he got away from it but hes had issues since with pain in his hands and feet, three weeks ago his ankle swelled up. They treated him with a tetnus shot even though there wasn t any sign of cuts, scrapes etc. The next day he explained his whole body hurt, they gave in antibiotics. A day later he was worse they had him do blood work to see if there was bacteria, there was not. He now has had blood work done for immune issues, the test was done over a week ago nothing from the docs yet HE is stil miserable, his swelling in his ankle goes up and down. Hes a happy hardworking 30 year old coaches his daughters baseball, he has been reduced to needing help to get out of bed. Any ideas?
