### input:
Ive had plaque psoraisis on my arms,scalp and outer ear canals and diagnosed with psoriatic arthritis with painful knees and back.  Obtained pain relief from topical magnesium.  Have now developed rashes in skin folds on abdomen and under breasts.  Is this from the transdermal magnesium or have I now developed flexural/inverse psoraisis?  I want to continue w/transdermal magnesium for pain relief but need to know if that is the cause of these rashes.

Hi, As you said you suffer from plaque psoriasis with psoriasis arthritis. I would like to say few things about psoriasis.... Psoriasis is a chronic relapsing and autoimmune disease. You may be having scaly plaques on various parts of the body, scaly lesions on the scalp. Exact cause is not known. Genetic tendency, autoimmunity, stress, Chat Doctor. .etc. may be responsible for precipitation and exacerbation of psoriasis. You have now developed lesions under breasts and in skin folds. It may be either candida intertwine or flex oral psoriasis. You consult dermatologist for firm diagnosis and treatment. I usually recommend cap accretion 10 mg twice a day along with methotrexate 15 mg weekly in three decided doses 12 hourly...for psoriasis. This may be taken for long time till good response. Blood tests may be done to monitor the treatment. For itching, you may take antihistamines like levocetirizin... Avoid steroid, as there may be severe flare up after stopping it. For skin fold lesions, you may take antifungal like itraconazole and do application of antifungal cream like clotrimazole. You may apply mild steroid cream or calcitriol point on the lesions on the psoriasis lesions. You may apply moisturizer to improve the skin texture. Furthermore, you should avoid soap bath for few weeks. And you should be free of stress and worries as that might worsen psoriasis. You might get good result. I hope you got my answer. Thanks.
