Dear Welcome to HCM We understand your concerns I went through your problem description. I suggest you not to worry too much. Froth on your tongue could be due to reflux disease, candidiasis or fungus infection. But you need to be sure that it is really froth and not just saliva. The hot sensation you are talking about could be nothing but your anxiety unless you are suffering really from fever. Just confirm these things and then you might see a physician. You might need psychological counseling., I am more than happy to provide telephone psychological counseling through healthcaremagic. Contact me through customer care, www.healthcaremagic.com. Hope this clears your doubts. Available for further clarifications. Good luck.
