Mid September (fall - in N. America) in 2004.
6 weeks after visiting Michigan and camping there - may have gotten lyme, but zero herx on doxy, Zithromax, Flagyl or clarithromycin.
Had a flu-like illness, but no vomiting, just numbness and weakness that moved up my legs. The acute episode resolved in a week, but it took 3 months for me to be able to jump or jog with any coordination and I've had worsening post-exertional fatigue since. I can force my way through a CPET bike test - my oxygen drops to 93%, my HR stays at 140. The doc told me - you are actually in good shape - you didn't slow down on the highest resistance, but your VO2 max is reduced and something is off with your HR and oxygen, but I can't put my finger in it.
PDK enzyme inhibition makes total sense, maybe the low O2 is from a touch of diaphragmatic weakness.
