WHAT YOUR HANDS CAN TELL YOU ABOUT YOUR HEALTH

Your hands could say a thousand words and if you care to study them closely and observe the changes that are happening, then you are sure to pick up some of those telltale signs of some alarming aspects about yourself.
Your finger nails are the furthest most point from your body, and could tell you if you are suffering from a skin cancer identified by doctors as "Acral Melanoma", very common among those with darker skin tones, where it would be shown with either a brown discoloring or black stripes under the finger nails.
A red coloring too would not bode well as it shows that you could have anti immune diseases, which can be identified as "Lupus" or "Rheumatoid Arthritis". If you find anything of the sort, a doctor would need to be consulted.
Swelling of the fingers is also not a good sign and could invariably be something not very serious to very serious and the best would be to consult a doctor and obtain a diagnosis.
