I saw white stuff on my throat a week ago this past Sat. By the time I got in to my appt. last Tues. it was on my tongue. 3 wks prior to noticing this, I had some steroid injections in my back by a diff. Doc. When I went to my reg. Doc. last Tuesday he prescribed Nystatin Oral- you Swish & Swallow every 6hrs; Amox 875mg every 12hrs; Triamcinolone Paste for the corners of my mouth. The past wed. I had another steriod injection. I went back to my reg. Doc. yest. Tues. the 16th & everything was good. But last week when I went to him he done a CBC, CMP, & I asked for HIV test because of the Medical Field I was in & things I seen is why I asked for test. Everything came back good. What can I do not to get this again or how do you get it? I brush & rinse my mouth with Listerine. My potassium & mag had been low (I have heart disease) But, numbers look good now. I was using alot of Fluoride toothpaste & fluoride mouth wash. I was told to stop & use Colgate. Just curious what can cause thrush. I had ate catfish from a restaurant the day before getting sick, it didn’t seem to be cooked all the way done, not sure. Any Help or Answers to help keep it away!
