question: my 9 yr old (wt85lbs, 4 5 usually healthy as a horse)has more blisters than my sons did they never had blisters on their hands or feet but they all had fevers, sore throats, vomiting, blisters in theirs mouths my 2 oldest have 1 on their outter lips and awfully bad breath. one thing i haven t really seen with the HFMD is red irritated bleeding gums. my 3 yr old bled when i brushed his teeth as if i brushed with razor blades, and after a day of not brushing he smiled and blood seeped out of his gums, the next day my 6 yr old woke up with with a mouthful of blood and plaquie blood covered all over his teeth. now my 9 yr old seems to be in more pain than the 2 of the boys (6 yr old wt 54lbs 48 ? usually healthy too and my 3 yr old wt 31 lbs has had rsv problems in past) together:( she even has a blister on her tounge which hurts even when she drinks water. i don t want her to become de-hydrated. what is good for her blisters. she says she has a hard time swallowing because her throat blisters hurt. and she has a loose tooth that is in major pain that looks really red around it we ve seen 7 dr s throughout all their visits and none diagnosed HFMD a teacher at my sons school did, it s seems right but not sure bout the bleeding gums. so in short they weren t diagnosed by a dr. but they have most of the symptoms of HFMD but also with bleeding gums and severe blisters in my 9 yrs old smouth on her tounge and throat what is the best treatment to prevent de hydration? or SOOTHE THESE SORES : ( please help
