The feeling of ice water/pins-needles running down your leg can be due to spinal nerve compression. It can also be due to peripheral neuropathy secondary to diabetes, thyroid disorders, Lyme’s and lupus.
Whole body pain coming on and off can be due to multiple spinal nerve involvement due to ankylosing spondylitis or osteoarthritis. It can also be fibromyalgia, chronic fatigue disorder, electrolyte imbalalnce or peripheral neuropathies as mentioned above. So yes, they can be connected. Please discuss with your specialist. Hope this helps. Take care!
