# The questions people ask about PRP *PRP Injection Questions | PRP Injections Glendale* > Common questions about a platelet rich plasma injection, joint soreness, the number of treatments, warning signs, and clinic visits. What do people ask before considering PRP? PRP means platelet-rich plasma, made by separating a platelet-heavy layer from your blood. People want to know what it contains, whether it may help, and what happens at a visit. The answers stay short and state what isn't known. ## What is actually in platelet-rich plasma? A centrifuge is a machine that spins your blood into separate layers. The clinic keeps liquid with more platelets, tiny blood pieces that clump at a cut. Different methods can leave different amounts of platelets and white cells. ## Can PRP help every sore joint? No treatment helps every person, and most PRP research concerns knee arthritis. A knee result can't predict what will happen in your shoulder, hip, or tendon. An exam helps identify the sore area, but relief is never certain. ## How many PRP injections are needed? There isn't one number for every joint. Some knee comparisons found a small benefit from a course, meaning several treatment visits, while others didn't. Your exam, past care, and the PRP amount help guide the number of visits. ## What is the difference between leukocyte-rich and leukocyte-poor PRP? Leukocyte is the medical name for a white blood cell. Leukocyte-rich PRP keeps more white cells, while leukocyte-poor PRP leaves most behind. The names describe the contents, but they don't decide which type fits your sore area. ## When does joint soreness need prompt care? Get prompt care when fever comes with a joint that feels hot and swollen. Spreading redness or pus after a treatment also needs quick attention. After an injury, don't wait if you can't put weight on the joint or it looks out of place. ## What can I do before a clinic visit? Note when soreness started, which tasks worsen it, and the medicines you take. Bring old joint pictures from any scans, and keep movement gentle if it feels safe. Don't push through sharp pain; use your notes to explain the ache. ## An exam comes before a treatment choice QC Kinetix medical providers, the clinicians who examine your joint, may discuss regenerative treatments, meaning non-surgical care such as concentrated PRP made from your blood.
