I am experiencing ankle swelling. Apply heat or cold?

Depends. If this is from an acute injury like a sprain, cold would be better. If this is more chronic or happening at the end of the day you would be better off using a compression sock. Let me know if I can be any more help.
Either way or both. Depending on the proximal cause of the swelling, the ankle can be treated with either heat, bold or both. Generally cold is for a more acute or recent injury. Heat can help with a chronic issue, mainly to increase blood flow and to promote healing.
Cold. At 26 y/o you should not be having swelling unless you are very overweight or wearing non-supportive shoes. If neither is the case, I would speak with your primary care doctor.

Unreliable. I'd be concerned about a kidney infection. These estimated gfr's derived from spot creatinines are subscientific -- there's even an adjustment "because people of african descent are more muscular" -- and i'd both you and your physician to focus on how you look and feel rather than on numbers that are at best intended as guides.
