Hands rely on the normal function of many body systems to work properly, so doctors often look to them for signs of illness and disease. Our hands can be excellent indicators of the state of our underlying health, especially when something’s not working right. Their form, function, and appearance can offer important prognostic and diagnostic clues.
Some warning signs/symptoms include:
- Weak hand grip
- Tiny red bumps or blisters
- Numb or tingly hands
- Trigger finger
- Red scales or pus-filled bumps
- White, blue or red fingers
- Hand tremor
- Purple finger nodules
- Hand pain, stiffness and swelling
