Noxious input to the spinal cord is known to produce central sensitization, which consists of allodynia , exaggeration of pain, and punctuate hyperalgesia , extreme sensitivity to pain. Two types of mechanical hyperalgesia can occur: 1) touch that is normally painless in the uninjured surroundings of a cut or tear can trigger painful sensations (touch-evoked hyperalgesia), and 2) a slightly painful pin prick stimulation is perceived as more painful around a focused area of inflammation (punctuate hyperalgesia). Touch-evoked hyperalgesia requires continuous firing of primary afferent nociceptors, and punctuate hyperalgesia does not require continuous firing which means it can persist for hours after a trauma and can be stronger than normally experienced. In addition, it was found that patients with neuropathic pain, histamine ionophoresis resulted in a sensation of burning pain rather than itch, which would be induced in normal healthy patients. This shows that there is spinal hypersensitivity to C-fiber input in chronic pain. 
Winstrol (Stanozolol) is an Anabolic Steroid that was derived from Testosterone in 1962 by Winthrop Labs . The original purpose of this steroid was to help treat people suffering from anemia, it is also often used for veterinary purposes. This high anabolic, low androgenic steroid does not bind to the androgen receptor. For this reason Winstrol is considered a weak steroid in terms of its muscle building properties, it does however cause great increases in strength. Stanozolol is also a popular steroid for females due to its low androgenic properties it makes it a safer choice as side effects such as voice deepening and facial hair are a lower risk when compared to steroids such as Dianabol . This doesn’t mean females should use Winstrol as irreversible masculine side effects are still a risk.
