Hi.. Thanks for the query.. Well, first of all you should get an Oral examination done as oral and gum infections can cause a distorted taste, bleeding and wired feeling from tongue.. Other cause can be acid reflux that should be checked.. In case if nothing is ruled out then you can proceed for further investigations.. However you symptoms does not completely point towards mold illness, but any confirmation can be done after proper investigation.. As of now you can start doing warm saline gargles, chew flavoured sugar free chewing gums to mask bad taste, drink plenty of water to cub dehydration and keep the tongue clean using a tongue scraper.. Hope this helps.. Regards.
