Raynaud's Disease - Patient's self diagnosis.
We love the ingenuity of patients.
This lady noticed that her fingers on her left hand were unusually cold. So she bought nail polish that changes colour when the temperature in her fingers changed. The first picture shows that both hands are cold and her nail polish is purple (she had just arrived and it is winter in SA). The second picture shows the fingers on the right hand have warmed up (pink) but not the left hand (purple). I was able to explain to her that she has Raynaud’s disease.
