The first step with autoimmune conditions is to heal your gut. Osteopaths and other natural healthcare practitioners have known about this for over a century and been considered quacks for suggesting this.
However, evidence is now mounting that a deranged digestive system is the starting point for the immune system to begin to dysfunction.
There are many ways to do this and one such is the GAPS Diet.
Of course, lifestyle changes are not profitable for the medical system and so much of this is little researched or ignored in favour of expensive medication with its multitude of potential side effects. Most medication, as you have found out, is simply there to suppress your current symptoms rather than to create good health.
Removing processed foods, adding fermented foods (kefir is widely available now as is sauerkraut), prebiotics, probiotics and fibre from vegetables is a good starting point. Start slowly as with such a longstanding problem this will take time to create the changes needed.
CBD may well have a role in lowering the inflammation, aiding your pain and helping repair systems get to work in your body. It is also good at helping regulate the immune system and stress system so you may see other benefits too such as a lift in mood.
Generally I suggest people start with a medium strength oil if budget allows so you get a good hit cannabinoids to start with, if you start too low and nothing really changes there is a temptation to think CBD doesn’t work for you when it may be simply that you needed to take a stronger product to start with.
Once you see benefits you can always go to a lower strength product next time around.
So this would point you towards either Signature Blend No1 or No2 or the Absorb Pure. The general rule is that the oils are calming and the Absorb range more energising so use that as the starting point of which to choose.
