Hi Mikey85
It's really important to get doc to check you out but if it is a candida overgrowth you could try oil pulling. Swishing eg olive oil in your mouth for 5 min and spit. Worth a Google, I may have left out bits. Also take control of your foods, low carbs, probiotic, fermented foods. Also contrast showers (alternate as hot as u can tolerate to as cold to stimulate your lymphatic system). If it's candida oral thrush is where it's showing in obvious ways but it's all happening in your gut and you need to get back in balance. It can cause such wide ranging symptoms that are quite vague so hard to get a GP to take it seriously. Getting the bad bacteria under control is doable and so worth it, give yourself 7-8 weeks. Oh and watch your stress levels, plenty of stress around us these past few months..
Wishing you good health
