[|Human|] I have been having right lower back/hip pain for months that is severe. Worse at morning, night, standing, sitting. I have high potassium. Diagnosed with Clark s Level 4 Melanoma of right thigh in 2010. Surgically removed. No chemo or radiation. MRI of back l spine shows synovial cyst at l4-l5. PET scan of whole body shows suv uptake of 4 in right jugular chain lymph node. Please help!
[|AI|]  Hi, Synovial cysts are not believed to be a significant contributor to the symptom of low back pain and should not be aggressively managed unless they are known to take up gadolinium contrast dye in which case surgical removal of the cyst with pathological examination may be warranted.  If the PET scan does not show any increased activity in the hip region on the right then, it is not likely to be due to any type of metastatic spread of the melanoma.  Conservative exercise and PT regimens are your best options to treat the pain along with OTC analgesic relief such as ibuprofen or Tylenol. Hope I have answered your query. Let me know if I can assist you further.
