One thing I've learned, is if you have pain you have inflammation. I don't know if you heard of glutathione, but research shows that your conditions is related to low glutathione level.
Many medical problems respond well to glutathione treatment in conjunction with standard medical treatment. Lung problems such as asthma and skin problems such as Psoriasis may all benefit from glutathione supplementation. This is a master antioxidant that is endogenous one, the only one your body make's. Look into it, I believe it will provide you better support.
