Hi i am Dr Ahmed Aly thanks for using healthcaremagic site , I had gone through your question and understand your concerns .. In my opinion i think your MRI will show if you have any kind of disc herniation which may be the cause of your cervical radiating pain . index and thumb numbness means that you have a kind of neurovascular compression usually the median nerve . this case is common and by electomyography may show carpal tunnel syndrome to properly diagnose it . I think you may use painkillers like advil tab when needed , B12 supplementation , muscle relaxants , hot massages with topical gels are effective for most of cases . You may try previous instuctions till your MRI and EMG shows exactly the main cause of your numbness and pain . Please click and consider a 5 star rating with some positive feedback if the information was helpful. Wish you good health, Any further clarifications feel free to ask.
