Lately my quadriceps have been feeling drained, numb, like they are falling asleep in evening hours. Menthol and arnica rubs before bed helps. I exercise daily, eat raw organic food (no sugar, no salt, only a little complex carbs, etc etc) considered excellent health by doc except one factor: I mysteriously lose all the ferritin in me every 8 months for no identified reason. (down to a lab result of 10 under ferritin tests. Hemoglobin normal) Could the two conditions be related - I am overdue for my feraheme as I lost my medical PPO insurance a couple months ago.
