It is a muscular spasm and is due to the excessive stretching of the muscles and you will get better in a few more days once you get off of this spasm. Oral medications you are on are all fine and no extra medicines needed at this moment. I suggest you to apply Voltaren gel on the back and massage it gently. Physical therapy is also very effective for this pain. Your primary care physician will help you refer you for the same. Take a rest and keep a balanced healthy diet.
