Your Senses Alert You

The nervous system has a specific sensory system or organ, dedicated
to each sense. Humans have a multitude of senses . There are following five traditionally recognised senses:-

Sight (ophthalmoception),
Hearing (audioception),
Taste (gustaoception),
Smell (olfacoception or olfacception) and
Touch (tactioception)

Your sensory organs can offer warning signs of serious health problems. See following few symptoms and their meaning:-

Loss of Smell

Cold and sinus infections can temporarily knock out the nerve ending responsible for smell. If your sense of smell does not return in a week or so, or if you lose your sense of smell suddenly for no apparent reason, visit to doctor. It may indicate nasal polyps or benign growth in the nose and may also be associated with brain tumors or diseases like Parkinson's and Alzheimer's.

Strange or Foul Odours with no Apparent Source

Smelling rotten eggs, burning electrical wires or other phantom odururs may be a precursors to serious conditions such as epilepsy or brain tumors. It may also be a reaction to prescription drugs, such as some thyroid and antiseizure medications.

Loss of Taste

Most people mistake a loss of smell for a loss of taste, since the two sensory organs are so closely related. Put a pinch of salt on your tongue. If you can taste it, then what you have lost is your sense of smell. If you can not taste the salt, see your doctor. Loss of taste can indicate a stroke or brain tumor.

Tingling, Burning or Numb Sensation

Unless your arm has fallen asleep from lack of use, any suspicious tingling or burning sensation in your limbs, especially in your fingers and arms, could be an early warning sign of heart attack or stroke. If tingling skin is accompanied by a feeling of pressure on the chest, call for emergency help.
