Now their making people wear masks to get lab test done. These masks don't provide any protection from viruses. After complaining about pain in my legs for 4 years I was finally sent for ultrasound CT scan and an x-ray. Then was preferred to a vascular surgeon for stents to be put in my legs but by that time it was too clogged up and they couldn't even put in the angiogram. The surgeon told me as it last resort they would put in tubes if I get gangrene. User's recommendation: Avoid.
