I had cervical spondylosis since many years. As such my otho asked me to take a MRI cervical spine.In that he found that there is  very small syrinx in the size of a small rice grain at c4 and c5 level .If burning sensation in ribs and hands and legs is one of its  symptoms,  then i had it right from 1976.   1.  Is there any medicine to completely dissolve the syrinx? 2.  As  there is no progress since many years, if at all it was there since many years., do i just keep it away from my mind and forget about it? My ortho asked me to take contrast MRI .  3. Can i postpone the same for a period of 3 months to see whether there will be any progress or not by undergoing regular MRI at c4 and c5 level after the end of 3 months period? 4. If there is no progress , can stop going for further investigation ?kindly advise and give your expert opinion.
