Armpit Pain, Tingling And Numb Fingers, Chest Pain, Difficulty Sleeping. Should I Be Worried?

Hi, What you are experiencing is called Radiculopathy . It basically suggests entrapment of a nerve root in your cervical spine in its origin or course. It is somehow not so uncommon now in younger population and we like to call it industrial neck pain, since its prediliction towards people working in computer related industry. If it has been persistent or even increasing since few days, you need to visit your orthopaedician. Depending upon the clinical findings they might ask you to get an MRI done, which shall help establish a diagnosis and in turn allow one to formulate a treatment plan. Let me assure you that this is temporary and self limiting illness that usually the treatment goes in following lines: rest, lifestyle modifications (namely- avoiding pillow while sleeping, following a healthy diet plan, maintaining suitable posture while working on computer/driving, avoiding any activity that strikes neck discomfort), medications (that your physician prescribes) and most important physiotherapy ( in form of neck exercises, cervical traction if required along with local ultrasonics). Hope this will helps you. Regards.
