Hi, I have read your query. About 1 in 200 people are born with an extra rib called a cervical rib. In some people it may cause pain due to compression of nerve as in your case so I am advising you to do stretching exercises, exercises to improve posture and exercises to increase muscle strength and endurance. These exercises are uploaded on youtube.These exercises may all help to open up the thoracic outlet and relieve the compression. You may also need to modify or change your work or sport activities. This may involve looking at the way that you sit in a chair or at your desk. An occupational therapist may be able to help with this. You may take medicines such as non-steroidal anti-inflammatory drugs (NSAIDs) - for example, ibuprofen - may be helpful in relieving pain in some people. Paracetamol or stronger painkillers may sometimes be needed. Other treatments occasionally tried include a group of medicines called calcium-channel blockers and botulinum toxin injections. If pain is not relieved then surgery is the last option. Physiotherapy may be helpful for some people and may include stretching exercises, exercises to improve posture and exercises to increase muscle strength and endurance.
