Many factors. May be diabetes or something completed unrelated like a pinched nerve. You should be promptly evaluated by a physician.
Carpal tunnel. Carpal tunnel syndrome (cts) occurs when the wrists are extended (held upward). When you type for extended periods, you must keep your wrists neutral or downward to avoid this injury. All it takes is one of those gel pads in front of your keyboard! I have one for my mouse, too. As for the other issues, you need to take breaks and stretch. Maybe consider retraining into a job with no keyboard!
My hands go numb all the time my fingers ache can't make a fist with right hand and right arm in pain?
Get checked. That sounds like carpal tunnel syndrome or another nerve compression syndrome. You need to get this taken care of before permanent nerve damage occurs.
Positional. Carpal and cubital tunnel syndrome are increased by the bend posture of the wrist or elbow. Leaning on the nerve for prolonged periods can also increase nerve compression.
Carpal tunnel. It certainly could be carpal tunnel syndrome, a pinched nerve in your wrist which makes your fingers go numb. See a hand surgeon for an examination and treatment.
Carpal tunnel. The constant vibrations from the MC engine transmitted to the grips may cause carpal-tunnel type symptoms, which you are describing. Neurosurgeon or hand surgeon can figure it out.
Consultation, EMG/NCT. Bilateral hand numbness can be commonly caused by either systemic issues like diabetes, vitamin deficiencies etc or can be due to peripheral causes like nerve compressions in the neck, elbow or hand. See your pcp who will refer you to a neurologist. After the investigations you will get referred to a hand specialist if you have ulnar or median nerve compressions for surgical release procedures.
Postural compression. Some considerations include pinching at the wrist or elbow, but maybe more proximal issue such as thoracic outlet syndrome. Might consider median compression at wrist, ulnar at elbow. Likely, this is currently rather mild, but if becoming progressively troublesome, have your doctor look at it.
Many conditiond. Go to see you dr.
