so, you’re getting some numbness or tingling in your hands and fingers? This article will briefly explain some of the reasons you may be experiencing this discomfort, which can feel like a mild pain, pins and needles, numbness, tingling, or a heavy feeling in your hands or arms.
Vascular Cause – the blood supply to the arms passes through the shoulder area. An important location to consider outside of what people typically consider is the area underneath and behind the clavicle bone. It is this area where most of the anatomy going into the arms originates. Problems there will likely cause arm problems. With vascular causes, look for swelling or discoloration.
Some of the main causes of vascular insufficiency leading to arm, finger or hand numbness or tingling include:
-traumatic – when an injury or accident causes damage to the arteries feeding the arm or hand.
-compressive – when a blood vessel is compressed causing decreased blood, such as when sleeping with your arm under your head and waking up with your arm “asleep”. Other times, muscle spasm can squeeze a blood vessel, or postural distortions can stretch (traction) a vessel and decrease the diameter enough to decrease blood flow.
-tumors/malformations – tumors or deformed blood vessels can block blood flow.
Vascular problems may occur more commonly in individuals with certain diseases such as diabetes, hypertension, or kidney failure, or in dialysis patients. Occupational exposure (vibrating tools, cold) can be a factor, and smoking also can aggravate and cause vascular disease. – Source
Neurological Cause – damage or interference to the nervous system can cause symptoms like pins & needles, numbness or tingling. Quite often the area to look to is the same as with vascular issues – the area behind and underneath the clavicle bone. It is here that many nerves exit the spine to innervate the upper extremities. Problems here, or right at the spine, often show up as pain or numbness in the hands or arms.
Some of the main causes of neurological numbness or tingling include:
-trauma / disc injury – if the vertebral discs of the cervical spine (the part of the spine that comprises the neck bones) are injured or inflamed, this can irritate delicate nerve roots and cause pain or numbness in different parts of the arms. Other traumas, such as bending the head and neck sideways too much (especially by impact with something) can tear the nerves or completely sever them, and cause paralysis or neurological deficits in the arms.
-tumors – tumors on or near nerves can pinch the nerves.
-vertebral misalignments – commonly called “subluxations”, these spinal misalignments put either direct or indirect pressuree on the nerves that feed the arms, and cause pain or numbness into the arms or fingers.
-muscle spasm – hypertonic, spastic muscles can put pressure on nerves.
