Psoriatic arthritis

Patient: Hello. I first had symptoms of severe muscle spasms in my calves, then my quads and knees. The lower half of my legs both swelled with severe pain and swelling around the knees. I went to rheumatologist who diagnosed me with psoriatic arthritis. She drained 1 cup of fluid out of right knee and 3 4 cup from left knee. I am on methotrexate 17.5mg per wk. In the last month however, my right elbow has swollen with muscle spams in forearm. Along with severe neck pain and spasms. Lateral flexion and rotation virtually nil. My RA factor came up negative. I am a Type 1 diabetic and have controlled hypothyroidism. Inflammatory levels in blood extremely high. It seems to be progressing so quick. ?????? What do I do???
