Hi
Welcome to the forum!
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, canal stenosis, bone disease, spondylosis, poor posture etc.
Use a hard bed to sleep. Avoid a pillow. Roll a towel and place it under your neck while sleeping. Initially this will be uncomfortable but with time the acupressure will do wonders. Use an analgesic cream or spray. Anti-inflammatory drugs help. A good physiotherapist can teach you some exercises which will help you a lot. A MRI of the cervical spine 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 physiotherapy to traction, cervical collars or even surgery.
It could also be due to high blood pressure so please get your BP checked.
Hope this helps. Do discuss this with your doctor and get yourself examined. Please let me know if there is any thing else and do keep me posted. Take care!
P.S.--the past couple of weeks i have been getting more slower in the sense of exhaustion and i feel like just falling over and closing my eyes almost everyday. I live a healthy lifestyle so im sure it has nothing to do with weight issues or unhealthy eating.
I just dont know what to do.
I'm tired and dizzy and my neck is killing me.
