The doppler ultrasound showed good blood flow in the carotid arteries (both right and left). They said I can do whatever I feel up doing, within reason. My speech, especially with S-sounds, remains a trifle problematic but I have a speech therapist and we're working on it. Saying something like, "Sue sold Susie a slew of slaw" would be come out as, "Shoe shold Shushie a shlew of shlaw" -- or at least that's what I hear and others say my speech is fine. That is why I'm not speaking at the Inauguration next week.
