hi shari. I´m physical therapist. My opinion is that you should keep you money. There is not any oil that will stop your pain. May be you can find some oil that with massage makes you feel better. But i tell you that the oil is no more than 20% of the effect, and massage the 80%. If you feel that massage is good for you, ok, do it,m but don´t spend your money in expensive oils.
But you ought to know that this will not cure you at all. It´s just a treatment that could make you feel less pain.
Whe we have a flare, we have pain that comes from our joints inflamation, and pain that comes from the muscles. the muscles are more tense as a protection reaction (they make the joints move less, and then, you feel less pain from the joints), but if this strain is kept for some time, the the muscle starts to give pain.
Then, the massage is going to improve your muscle pain, but that is all (in some cases, the muscle pain may be 50% of the pain that the patient is suffering, and to quit this may be a great improvement). This may be useful for you, or not. It depends if you have a lot of muscular pain or not.
PS:How are you?. I read in a past post that you were a little bit desperated.
i hope you´d be better now.
