I went into a medical aid unit yesterday after suffering lower back issues (spasms) from simply bending over. This is not the first time it has happened, been a few years though, and it was about 16 hours before I was able to get a ride in. They injected me with a muscle relaxer (not sure what) then prescribed Diazepam 5 mg to take every 8 hours which I started at about 11 am yesterday and took as prescribed. I woke up this morning with a sore throat, thought it might just have been dry in the house (oil heater), it has not gone away, and I don t feel the meds are helping my back, they just make me sleepy. Not sure if I should go back to get meds changed?
