Ever since its discovery and availability for sale and use in the late 1940s, lidocaine has become an exceptionally commonly used medication. In particular, lidocaine's principal mode of action in acting as a local anesthetic that numbs the sensations of tissues means the agent is indicated for facilitating local anesthesia for a large variety of minor surgical procedures. It ultimately elicits its numbing activity by blocking nerve activity so that local tissues that have the medication applied are temporarily (approx 30 minutes) incapable of feeling pain sensations.  Lidocaine's local anesthetic action sees its use in many medical situations or circumstances that may benefit from its action, including the treatment of trigger points and joint contraction.Lidocaine is currently available as a relatively non-expensive generic medication that is written for in millions of prescriptions internationally on a yearly basis. It is even included in the World Health Organization's List of Essential Medicines.

What is platelet-rich plasma?
Using a patient’s own blood cells to accelerate healing in a specific area of damaged skin. Platelet-rich plasma consists of two elements: plasma, or the liquid portion of blood, and platelets, a type of blood cell that plays an important role in healing throughout the body. Platelets are well-known for their clotting abilities, but they also contain growth factors that can trigger cell reproduction and stimulate tissue regeneration or healing in the treated area. Platelet-rich plasma is simply blood that contains more platelets than normal.To create platelet-rich plasma, clinicians take a blood sample from the patient and place it into a device called a centrifuge that rapidly spins the sample, separating out the other components of the blood from the platelets and concentrating them within the plasma.The nutrient rich solution is then applied to a special dressing placed upon the wound to maximize its contact with the tissues that require healing and those that require cleaning.This treatment is effective for chronic wounds due to diabetes, pressure sores decubitus ulcers and venous stasis.
