This condition causes blood blisters to form on the inner cheek, gums, tongue and/or the roof of the mouth. It is caused by the herpes simplex virus 1 and symptoms, like pain, a burning sensation, fatigue and fever, will be felt. You will consistently find a blood blister in the mouth of alcoholics, because alcohol can cause ulcerations inside your mouth.
Sudden hearing loss after stroke is less common than other neurological impairments, but it may be the initial presentation of vertebrobasilar ischemia, which is more common in the presence of vascular risk factors (Kim & Lee, 2009; H. Lee & Baloh, 2005; H. Lee & Cho, 2003; H. Lee et al., 2002; H. Lee, Whitman, Lim, Lee, & Park, 2001).
(A normal conversation is 60 decibels.) In nine out of 10 cases, sudden hearing loss affects only one ear. Though there are about 4,000 new cases of sudden hearing loss a year, doctors figure out the cause only 10% to 15% of the time.
