My upper back it hurts all the time... anybody knows why?!

The upper back and neck region is the most complex area of our body because of the many joints and how those joints work together.
The two most common reasons for upper back and neck pain are trauma and muscle imbalance, the latter being responsible for what are called "postural dysfunctions." These postural dysfunctions cause abnormal alignment of the head and shoulders and abnormal positioning of the joints that lead to increased wear and tear on the joints, muscles, and ligaments--even discs.

The majority of the complaints range from local pain to radiating pain, weakness and pain in the arms, pain and irritation with any movement of the upper body, morning pain and stiffness.

Your condition can be diagnosed by an MD, a physical therapist, or a chiropractor. But in order to get the most comprehensive picture of your condition, you may need to see more than one professional.

Cortisone injections, prescriptions for muscle relaxants or non-steroidal anti-inflammatory drugs (NSAIDs), and bed rest are most commonly employed.

Chiropractic care and physical therapy can offer spinal mobilizations, hot packs, ultrasound, electrical stimulation (TENS), cervical traction, and therapeutic exercises.

I hope this helps you. And good luck.

Get it X rayed to confirm that there is not slip disc. If not it could be rheumatism. Go check with the specialist.
