Your normal sweetie, you are just feeling anxiety trying to take over your day. Phenazopyridine treats the pain, burning, increased urination, and increased urge to urinate. Brand name is Pyridium. It really works fast to stop the burning thow. You can buy this drug over the counter as I keep it on hand just in case. Sometimes it will get you through until you can get to the Doctors office with a urine sample.
Sulfamethoxazole is a sulfonamide drug that is often the drug of choice for UTI. I am sure they did a culture on your urine and if comes back indicating this is not the right med for the bacterial infection you will hear from your Doctor. This is a med known for causing upset stomachs so do try to take it with food if you can.
Now here are some big hugs to go with those big deep calming breaths you are taking and know that we are all right here and you are safe.
By tomorrow you should be feeling a lot better. Use your pain medication and try to catch a nap.
Drink lots of fluids and yes cranberry juice is still in vogue for UTIs.
How did you do on your meds last night? I am hoping it went well. Let us hear from you.
