Need suggestions for instant relief from cording

I guess it's a good lesson for others. If you have cuts on your hand, then lymphedema and a cord, and your cord gets suddenly more painful than usual and then your skin gets red and mottled get to a doc quick. The specialist doctor just told mottled skin is an early sign of cellulitis and sepsis and lymphedema puts us at higher risk of infection. I also had a fever of 38.5 and didn't know it.
