Yes, definitely. Lyme loves DS's left knee and right shoulder, mostly the knee. I think that is normal for many but probably not all since Lyme symptoms can also be so random. The tingling, pain, swelling and numbness have gone away for DS but that was well into treatment, probably much better by 6 months and gone at 1.5 years. Hopefully you'll get there sooner!
