# Can a knee result tell me what will help my back? *Knee, Hip, Shoulder and Back | Stem Cell Clinic Peoria* > A stem cell clinic Peoria guide explains why stem cell therapy for back pain cannot be judged by results for a sore knee. ## Why can't one answer fit every sore area? Peoria paddlers at Lake Pleasant may notice shoulder soreness after a day on the water. A result for a knee can't explain that shoulder or tell you what caused it. The back, hip, knee, and shoulder move differently and can hurt for different reasons. I'd begin with the sore area, the hard motion, and what the exam finds. ## What has to match before a result helps me? A result won't help unless it involves the same body part and kind of damage. It also matters which treatment was used and when the result was checked. A knee with mild wear isn't the same as one with severe damage. Your age, health, past care, and daily limits can also affect the choice. Ask this plainly: Did the people studied have the same joint problem I have? Then ask whether they received the same shot now being offered to you. ## What natural pain treatments could come up? QC Kinetix uses natural pain treatments as a label for shots prepared from your blood. The clinic's medical providers are licensed medical workers, though you'll need to ask if yours is a doctor. One option is PRP, meaning platelet-rich plasma taken from your own blood. Staff spin the blood, keep its platelet-heavy part, and give that part as a shot. Ask what soreness or swelling may follow and when normal movement can begin again. You'll also want the total cost and the likely number of visits in writing. ## Which back warning signs can't wait? New leg weakness or numb skin where a bicycle seat touches needs urgent care. That skin is between your legs and around your bottom, sometimes called the saddle-area. Trouble controlling your bladder or bowels also can't wait for a regular visit. Fever with severe back soreness or a major fall calls for prompt care too. Without those signs, a visit can check walking, strength, feeling, and back motion. The examiner can then explain which choices fit your back rather than a knee. ## Sources 1.
