I didn't have much jaw pain as such but have a coated tongue every day which I brush off in the morning. Usually looks a yellowish colour when I spit it out.
Obviously only you can decide what is best for you, but with a compromised immune system it's almost impossible to get rid of a parasite infection before addressing the root cause as it were. At least that was the case with me and others I know.
I waited 4 months on a waiting list, no deposit or anything. Once I had my initial appointment everything happened fairly quickly from there on in.
I've had all of the work done now. It's very early to tell, but I definitely feel a bit different, a bit lighter like a weight has been lifted off me, but only time will tell I guess!
