Although it seems obvious in hindsight, 20/20 vision and all, it did not occur to me that allergy swollen eyes would be contraindicated regarding Downward Facing Dog in yoga. Now into self diagnosed Conjunctivitis, I look back in wonder.
Just as well, the instructor had indicated that the class would be doing Handstands, so I was already wondering "well what shall I be doing during that period?" Instead an early exit. Now I'm wandering around in a Benedryl induced haze.
Update: After phone consult, MOST likely allergies (vs Conjunctivitis)
