Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. [http://www.onelook.com/]
Nociception definition: The stimulus-response process involving the stimulation of peripheral pain-carrying nerve fibers (e.g., C-fibers, A-delta fibers) and the transmission of impulses along peripheral nerves of the central nervous system, where the stimulus is perceived as pain. (Taber's)

detection of temperature stimulus definition: The series of events in which a temperature stimulus (hot or cold) is received and converted into a molecular signal. [GOC:hb]
Touch definition: Sensation of making physical contact with objects, animate or inanimate. Tactile stimuli are detected by MECHANORECEPTORS in the skin and mucous membranes.
touch definition: group of senses by which contact with objects gives evidence as to certain of their qualities, as registered by mechanoreceptors in the skin and mucous membranes.
sensory perception of touch definition: The series of events required for an organism to receive a touch stimulus, convert it to a molecular signal, and recognize and characterize the signal.
