Taking copaxone (glatiramer) for many years for my MS. I have pain in my right big toe with inflamation. Could my body systems not want me to take it. ... Gout?

Need to reassess. At your current age, 77, you may no longer need copaxone, (glatiramer) and if you developed a secondary progressive ms transition, this drug would not be appropriate to handle that either. The pain in your toe could be gout, but other explanations may be considered. Yes, check your uric acid, but also update MRI of brain, and get full neurological re-evaluation.
Gout. It sound like you have developed gout but this has no relation to the medication you are taking.
