Hope your feeling somewhat better as you typed your question.
Pain is a unpleasant feeling, as this makes us take stock of our health. Almost 10 million people are affected by pain in the UK, so your not alone.
Firstly, stop lifting!
Secondly, have you seen and talked to your local GP? Having had an assessment, they may suggest pain killers (not ideal), or a form of cream. Ideally, you want to ice the area if the pain is causing issues.
Some questions I would raise with you:
Has this pain occurred more than once?
Does it hurt when you breathe?
Have/Did you have a work assessment completed?
Massage can help you, as well as Neuro Skeletal Re Alignment Therapy. Please see my website for further information http://www.aurora-aromatica.com
Once you've visited your GP, mention that this is an area that you want to pursue. If you live anywhere in my area, then I would be interested in treating you.
Wishing you Good Health!
