Can a problem in the neck cause finger pain?

If no prior neck injury that could suggest any possible cervical disc/joint trauma resulting in spinal nerve impingement, with your description and response to treatment on your neck (ineffective), it's quite straight forward that you've developed carpel tunnel syndrome. Other possible causes are far less likely unless you are assessed for but cleared of carpel tunnel syndrome. I would suggest you see another physio for 2nd opinion because at the end of the day, only physio and surgery can address carpel tunnel syndrome, but you don't want to delay it to the point that surgery becomes unavoidable. I hope this helps

After stuggling with pain for about 10 months and several physio visits, my GP finally ordered for a MRI of cervical spine and here are the results. 

Symptoms were Tingling and pain in both the arms and fingers. I am going to see my doc again in 2 weeks but great if any thoughts around how serious this issue is and what are the possible treatment options. Any suggestions is much appreciated.

Findings

There is loss of the normal cervical lordosis with a slight kyphosis present centred on the C4-5 disc. At C3-4 there is loss of disc signal and height. There is a diffuse disc bulge present more prominent in the left lateral position but no significant foraminal stenosis. No central canal stenosis.

At C5-6 there is also loss of disc signal and height with mild bulging of the intervertebral disc. Due to a combination of uncovertebral osteophytes and some facet joint productive changes there is moderate left foraminal stenosis with mild narrowing only on the right. Despite this there is no evidence of nerve root compression.

The remainder of the cervical intervertebral disc demonstrate normal signal in appearance. The cord is of normal signal and appearance. No abnormality is seen at the craniocervical junction.

Impression

Cervical spondylosis at C4-5 and C5-6 with mild left foraminal narrowing at C4-5 and moderate left foraminal narrowing at C5-6 with mild foraminal narrowing on the right at this level.

Hi Srini. 

It's difficult to make a conclusive view on conditions that I didn't assess, but honestly, neck and arm aren't really that challenging to diagnose. Once correrctly diganosed, depending on whether it's permanent damage or not (disc damage is permanent, but what causes pain in your fingers still needs a proper diagnosis, which I emphasized before) and how physio implement treatments (every physio has his own method of treatment approach based on his clinical experience), it really shouldn't take long for you to see the result. 

and yes, blurred vision can 'sometimes' be caused by neck problem, but depends on case to case. You can't just say every blurred vision in a person with neck pain is all caused by his neck problem.

You should really search and find an experienced physio, otherwise all this time and money wasted, and still not moving forward after months of stress. Our discussion will not help you make progressive improvement, as my advice can not be converted to treatments without assessing and treating you. You should refer your queries to your treating physio, coz only he can give you a definite answer after assessment. If there is no improvement seen and your treating physio can't justify why you need to return for review appointment, then you obviously want to get a second opinion. 

There are no dates on post on this site!   Not sure how long ago the question was asked and answered.

It's possible that the nerves for the fingers can be very slightly impinged anywhere from the neck to the wrist, including at the elbow.  Tight pecs, traps, front deltoid are some common muscles.  Make sure your elbow isn't wresting on a hard surface, and that your wrists have a soft support for keyboard use.  When your sitting at your desk think about where your shoulder blades are, squeeze them together a few times.  Shoulder often are hunched up and forward.  Your head should be above your body, use a mirror to check your actually doing this.  Your computer monitor should be high enough so that you look across at it, and it should be close enough to allow you to easily read from the screen.  Do the stretches your physio gave you regularly.

You don't have to have perfect posture all day, but each hour you should bring it back to an ideal position.  Move your shoulders up and down, and back.  Start to become aware of when your tired or stressed what your body does, do you lean on the desk and hunch forward.

Try all these things.  It won't improve instantly but if you keep up with it, your likely to see some results (since you mentioned that stretching helped).
