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).
Severe Hearing Loss Causes. When your hearing is normal, sound waves enter your outer ear and cause your eardrum and middle ear bones to vibrate. The sound waves then travel through your inner ear, which is a shell-shaped, fluid-filled tube called the cochlea.
