"i was prescribed this capsule when my pain in left thigh muscle became unbearable and i was not able to stand or walk. either this, or combined first 3 days muscle relaxant made my pain vanish. i was prescribed for 15 days and after 8 days, i forgot to take one night. i felt much better next day (after not taking).  as i am getting pain in knee joints, which i did not have earlier, i think, i will gradually stop it."
