Sweating is a normal process that helps in maintaining the right temperature for your body. Sweating occurs on the entire body but it would be more on the soles, palms and armpits and on the face. An individual is said to have excessive sweating if he/she sweats a lot irrespective of the temperature or activity level. In other words, a person will sweat excessively even if he is sitting idle and watching television. This would cause discomfort and embarrassment while taking part in social activities. In medical terms excessive sweating is called as hyperhidrosis and this can be managed by taking antiperspirants or sometimes by surgically removing the sweat glands from the body.

Pyoderma gangrenosum is a condition that causes large bumps or ulcers on the legs. The painful sores can develop anywhere on the skin but it largely occurs on the legs. It is believed to be caused by abnormal immune system where the body’s own immunity will destroy and damage the skin surface causing blisters. People with preexisting chronic disorders like rheumatoid arthritis or inflammatory bowel disease are more likely to develop this disorder. Painful ulcers can be controlled using powerful medications and by using anti-suppressing agents. However it is a rare disorder affecting only few people.

Papilledema is the medical term denoting swelling of optic disc. It can develop due to intracranial pressure, infections, or inflammation developed on the optical disc. One should not confuse papilledema with disc atrophy (that occurs due to loss of nerve fiber on the optical nerve). This condition can produce symptoms like headache, nausea and vomiting also apart from affecting the normal vision. Papilledema can cause blurred vision or flickering vision.

Normally the tongue has an extra layer of covering with fine hair like structures called papillae. But people with geographic tongue will not have these papillae thus exposing the patches on the tongue. These patches will sometime look like small islands with clear defined border resembling a country’s map. For this reason it is called as geographical tongue. In medical terms it is called as erythema migrans or migratory glossitis.

Bell’s palsy is a strange condition that causes weakness in the muscles of the face. Weakening of muscles of the face is sudden reaction that may change the appearance of the face. When the affected person smiles it will not be complete smile. One side of his face begins to droop and his eyes would resist closing as he continues to smile. Since the facial muscles are affected due to this problem Bell’s palsy is also known as facial palsy.
