You wrote this at midnight, and it is now 9am the next morning. Were you able to sleep?
I am confused, as you say you have a kidney infection...have you already been to the doctor and diagnosed with this? Were you given the antibiotics for this condition, or were they leftover prescription from something else?
There are over-the-counter (OTC) medications that you can use to relieve the symptoms of a tract infection that are painful. Ask the pharmacist at your local drugstore to show you the medications that are available at your store.
Are you able to go to the doctor today? Please let us know how you are doing!
