My son is now an adult. Years ago he had many symptoms like I did when I thought I had CFS but it was really lyme. He had a bit of Tourettes, which he grew out of.He was never diagnosed with Lyme. Seems pretty healthy for an adult now but is experiencing double vision that he says has gotten a bit worse over time. His eye doc says his 6th cranial nerve is affected and he is being sent for an MRI. I am wondering if it is common for Lyme to cause 6th cranial nerve palsy and if anyone here has had it and if it improved with treatment?
