20. Frequently Asked Questions
How long does a PRP treatment session take?
A complete PRP treatment typically takes 45-90 minutes. This includes blood collection (5-10 minutes), processing (20-30 minutes), and injection procedure (15-30 minutes). Additional time may be needed for ultrasound guidance or multiple injection sites.
Is PRP treatment painful?
Most patients experience minimal discomfort during PRP treatment. The blood draw is similar to a routine lab test. The injection may cause mild discomfort, but local anesthetic can be used. Some patients experience increased pain for 24-48 hours after injection as the healing process begins.
How quickly will I see results from PRP therapy?
Results vary by condition and individual. Some patients notice improvement within 2-6 weeks, while others may take 2-3 months to see significant benefits. The healing process is gradual, and maximum results are typically seen at 3-6 months post-treatment.
Can I take pain medication after PRP treatment?
Acetaminophen (Tylenol) is recommended for post-injection discomfort. Avoid NSAIDs (ibuprofen, naproxen) for 2-4 weeks after treatment as they may interfere with the healing process. Ice application and gentle movement are also helpful for managing discomfort.
How many PRP treatments will I need?
The number of treatments depends on your condition, severity, and response to therapy. Acute injuries may require only one treatment, while chronic conditions like arthritis typically need 2-3 injections spaced 4-6 weeks apart. Some patients benefit from annual maintenance treatments.
