What are some ways to get rid of the pain in my achilles?

Stretching. Of course, the treatment depends on your exact diagnosis, but many achilles problems can initially be treated with physical therapy, heel inserts, and pain medication. Surgery is sometimes recommended as a last resort. I recommend that you see an ankle specialist if you're symptoms warrant.
Wear a heel lift. In your shoe, wear strtching splints when you go to sleep. Eccentric achilles tendon stretches to name a few.
