Muscle aches and tingles

Here are several possible explanations from WikiAnswers users:

  • Vascular - There could be some reason for poor circulation to the arm/hand. This is very commonly caused by too much muscle tension in the scalene muscles or the the pec minor muscles. The blood vessels that supply the arm/hand have to pass through these areas, via the subclavian artery, to branch off into the arm. It could also be due to a misalignment of the shoulder. If a shoulder is misaligned in external rotation, it can put a stretch on the blood vessels that pass through that area to supply the arm/hand. In any case, a chiropractor is the professional to seek to correct any biomechanical problems within the body. Chiropractic adjustments can also have a valuable effect on the autonomic system, which affects the cardiovascular system.
  • Pinched nerve -This could definitely be a pinched nerve - either in your neck, shoulder, or arm. You need to be seen by a doctor (preferable an orthopedic surgeon) before you experience permanent damage.
  • Tendonitis
  • Migraine (hemiplagic migraine)
  • Stroke, Transient Ischemic Attack (mini-stroke)
  • Chronic Fatigue Syndrome/Fibromyalgia
  • Reynauds disease causes constriction of the blood vessels and usually your fingers get numb, turn whitish in color.
  • Angina
  • Repetative Strain Injury, Carpal Tunnel Syndrome- Using a mouse or keyboard, or other tools, in the same position for an extended period of time can be harmful. Google ergonomics or Carpal Tunnel Syndrome.
  • Cervical Disc Herniations:
    Cervial Disc Herniations can cause tingling, arm numbness and pain. It might be helpful to see a Neurosurgeon. They may run MRI's, Myelograms etc..

See a doctor.

I can do nothing to improve this detailed and knowledgable answer, but to say that most otherwise healthy people that have this symptom and are on a computer all day usually the computer use is causing this symptom.

(as the person above said though, see a doctor as SOON as possible, it could be anything above)
