Pete, how's the thumb? Here you go, some oils good for muscle/joint pain:
Clary Sage
Chamomile
Eucalyptus
Valerian
Lavender
Thyme
Blend 5-6 drops of oil with 10mls of carrier oil (grapeseed is the most commonly used) & massage in.
Or very soothing for muscle/joint pain.Make a compress by adding 2 drops of essential oil to 200ml of either hot or cold water, fold a natural piece of fabric such as cotton into several layers, soak in the solution, squeeze out the excess then lay over the affected area for at least an hour, resoaking at intervals.
Give it a try, you never know!
