Autoimmune diseases: when the immune system goes astray
Certain conditions, such as rheumatoid arthritis or Guillain-Barré syndrome, affect the nervous system. They can cause numbness, as well as muscle weakness. Pay attention to the gradual onset of bilateral symptoms or unusual weakness.
Poor circulation: cold weather and atherosclerosis to blame
Raynaud's phenomenon causes a temporary narrowing of the blood vessels, making the hands feel cold, pale, or bluish, often with tingling. Other circulatory problems, such as atherosclerosis, can also restrict blood flow to the extremities. To combat this: protect yourself from the cold, engage in regular physical activity, and have your cardiovascular health checked.
Cysts or tumors: a local pressure that should not be ignored
A cyst, such as a ganglion cyst, can compress a nerve in the hand. This often results in numbness, pain, or difficulty moving. Diagnosis is usually straightforward: an ultrasound is sufficient to detect this type of formation, which is most often benign.
