How do I get better at the start?
First, seek a healthcare professional to get a medical check.
Remain as active as possible without aggravating your neck, change your posture often, avoid sitting for prolonged periods, and break up your regular household routines into smaller time periods.
Get adequate sleep at night aiming for 7-8 hours. There is no perfect sleeping posture, just sleep in the most comfortable position. It is also beneficial to manage stress as best you can, as this can be a contributor to an increase in pain levels.
Consult your physio within the first few days of pain to get advice, an individualised exercise program as well as some hands-on treatment that will provide some short-term relief.
The initial program will involve gentle movements and stretches that will help to reduce the sensitivity in the neck. Over time this will then progress to more strengthening-based exercises that will help strengthen the neck so it is less likely to become injured in the future.
