Aromatherapy

Hi I am looking for somewhere/one to make me up an aromatheraphy mix/lotion. I have oesteoarthritis in my wrist, spondylo arthritis in my ankles, knees, back and neck and use this to ease pain as I cant take any medication due to also having crohns disease. This works wonders short term but I have almost run out and can't get it from the same person as i did last time. I have been looking online for someone for weeks but now getting very desparate can anyone please help with this
thank you
Mandy
