welcome to Health care magic.
1.You have already got done the
MRI which was needed, and findings are there, but no active treatment is happening - this is what i understood.
2.The reason could be, there might be some underlying medical conditions which are not supportive to take any active intervention / operation.
3.Age could be one of the factor where the doctor only can give some symptomatic treatment.
4.So be with the treating doctor - if you feel he is fine, responsible and answering your questions.
5.If you are not satisfied with doctor you will never get satisfied with treatment, so do the possible things you can do.
Hope it helps you. Wish you a good health.
Anything to ask ? do not hesitate. Thank you.
