UK - London - a tuberculosis patient waits in pain for an MRI scan wearing his mask

He is in great pain, no matter how many pain killers he takes the pain will not subside and he finds it difficult to concentrate, to talk or to walk. He has to wear his mask at all times when moving around the hospital. Francis lived on the streets before he was admitted to hospital and diagnosed with tuberculosis where he commenced a DOT, Directly Observed Treatment.
