Unfortunately I don’t have an answer for you. Kratom is not approved for use in the USA, although some former pain patients seem to feel it helps with pain. There are some potentially serious adverse reactions to its use, including addiction when stopping and prolonged withdrawal symptoms.
You don’t say what the drug was you were given 10 mg of or how long ago you took it.
Ice and heat patches can ease muscle pain, and some topical over the counter pain relievers may help.
