What Can Cause Tingling in Left Hand Fingers?
Two causes of tingling in the left hand fingers are carpal tunnel syndrome and Raynaud's disease, according to Mayo Clinic. Other causes of tingling in the fingers can be the fingers of the left hand waking up after "going to sleep," claims WebMD.
Carpal tunnel syndrome is a condition where pressure on the median nerve causes not only tingling but pain and loss of feeling in the thumb, index and middle fingers, claims Mayo Clinic. The discomfort is intermittent at first. The little finger is uninvolved. There is no one cause of carpal tunnel system, but people at higher risk include those who have disease that affect the nerves, such as diabetes. Conditions such as menopause, pregnancy and inflammatory disease also increase the risk. There are nonsurgical and surgical treatments for carpal tunnel syndrome.
Raynaud's disease also causes tingling in the fingers, claims Mayo Clinic. The fingers turn cold and may turn blue in response not only to cold but to stress. The tingling sensation happens when circulation resumes in the fingers. Medical professionals are not sure what causes Raynaud's disease, but there are two basic types. Primary Raynaud's disease does not have an underlying condition, while secondary Raynaud's is associated with diseases of the connective tissue, atherosclerosis, injuries including repetitive injuries, and smoking.
