Hi there, this is the first time I, ve written a post but have read with interest all the others and have found some terrific information and advice. I herniated discs L2 3 and 4about 18 months ago and have since run the gamut of conventional treatment without success and am currently awaiting orthopaedic review to discuss further options. I, m from NI and the waiting lists here are phenomenal. By the time you get anappointment, all the symptoms have changed. However what I really wanted to say was that 3 years ago I wasdiagnosed with psoriatic arthritis and take methotrexate to slow the progression of the disease. I have recently been told that this disease affects the lumbar spine quite badly and wonder if anyone can give me some relevant I formation or advicd about this combination.
