If there is tenderness on pressing the neck from outside, then this could be due to spinal nerve compression, inflamed sternocleidomastoid muscle as in TMJ, swollen lymph nodes if you can feel a mass, an abscess if you can feel a mass, a clot in the carotid artery or due to a muscle pull.
There is a chance that you have compression of the spinal nerves in the cervical spine region. This can happen due to overuse of computers, work involving straining of neck, herniated disc, canal stenosis, bone disease, spondylosis, poor posture etc. A MRI of the cervical spine and nerve conduction studies may be required. Please consult a neurologist. The treatment is to remove the compression. You have to discuss the best treatment option with a neurologist, which can range from medication to steroid injections to physiotherapy to traction, cervical collars or even surgery. Alternatively you can visit a chiropractor or a physical therapist and learn some exercises which you can do to relieve the compression, but consulting a neurologist is a must.
Use a hard bed to sleep. Avoid a pillow. Roll a towel and place it under your neck while sleeping on the back and between head and shoulder when lying on the side. Initially this will be uncomfortable but with time the acupressure will work. Use an analgesic cream or spray. Anti-inflammatory drugs help. Also, you must improve your posture while sitting and working. Take care!
