hi ! having diagnosed as early stage cervical spondylosis, the symptoms you have mentioned are related to it, but they have developed in very early stage of 18yrs for you. through homoeopathy you can be completely cured.
dont delay in consulting a doctor as it may complicate, because the rapidity with which the symptoms you developed is very fast.
Next Steps
consult a good homoeopath in ur vicinity, or else u can consult me thru contact or mail i can guide u for the treatment.
