I have been doing exercises for 8 weeks, given me by a PT for upper trap pain.
Sometimes certain injuries or chronic imbalances take awhile to correct and the time it takes will vary depending on extent of the injury, follow through on the the rehabilitation, and the individual – you should revisit the issue with your PT.
You are on the right track if you see gradual (though perhaps small) improvements in your pain. If you are not seeing any improvements whatsoever you may need to make modifications to what you are doing, again in concert with a professional – get a second opinion if necessary.
Alternatively you could see a massage therapist, that may help with reducing the symptoms of pain and discomfort while you seek remedies to correct the source and eliminate the cause of the pain you are having.
