Hi,
Sorry I can’t help give you insight to the blindness issues, as the only ‘loss’ of sight as such, that I’ve experienced has been fading colour – I’ve had lots of other sight issues, like double vision, blurriness etc but no actual loss of sight.
Regarding your sons leg issues, I have had the purple legs, which led to being diagnosed with POTS (Postural Orthostatic Tachycardia Syndrome). It came with much leg pain. I noticed my “Pulse Pressure” (which is the difference between the two BP figures, i.e. Systolic – Diastolic) was a related factor too, being very low when I had this ‘purple-leg’ symptom and pain.
