Key takeaways
- Acute injuries such as falls, sudden sharp pain, rapid swelling or inability to bear weight mean urgent care or your physician first.
- Pain lasting beyond two weeks, worsening, sharp or popping, or changing how you move deserves evaluation. Per Dr. Kendall Perrine, ND (Purist Natural Medicine, Arroyo Grande), that is the threshold where it is no longer just soreness.
- Physical therapy stabilises joints but cannot repair tendon and ligament tissue itself. Regenerative injection therapies such as ozone, prolotherapy and PRP are used for that gap, before surgery is ever on the table.
- Typical return to play: about one week after ozone treatment, about four weeks after prolotherapy or PRP.
- You do not have to leave SLO County for this. Regenerative treatment is available locally in Arroyo Grande.
First question: is this an emergency, or a lingering problem?
Go to urgent care or your physician now if you had a fall or sudden injury with rapid swelling, cannot bear weight, or heard or felt a pop with immediate loss of function. This article is about the other kind, the pain that hangs around.
Normal soreness fades in three to five days. Get pain checked when it lasts more than a couple of weeks, when it's progressively getting worse, when it's sharp or has a popping quality, or when it makes you limp or stops you mid-play.

What are your treatment options in SLO County?
Physical therapy is usually the right first step for lingering pain. It builds the muscles that stabilise a joint and addresses movement patterns, and many injuries resolve fully with it. SLO County has strong physical therapy and chiropractic options, and your physician can refer you.
The problem is when physical therapy helps but does not finish the job. Many players do their PT, improve 60 to 70 per cent, then plateau, and get told the next stop is a specialist or surgery.
Physical therapy builds the muscles around a joint to stabilise it, which is valuable, but it can't repair the ligament or tendon attachments themselves, and it can't regenerate cartilage. That's the gap regenerative injection therapies fill, before you'd ever consider joint replacement.

Regenerative medicine is the local middle option. Dr. Perrine works with exactly this plateau: if physical therapy helped some but not fully, that tells her the injury needs a nudge PT alone cannot give. Her approach starts with a thorough physical exam, then typically progresses from ozone therapy in Arroyo Grande to prolotherapy or PRP depending on the injury and your health history, with treatment courses running one to ten sessions by severity.
What are PRP and prolotherapy, in plain English?
Prolotherapy is a solution mostly made of medical-grade sugar water injected right into the injured area. It gently irritates the tissue on purpose, which signals your body to send its own repair crew and lay down fresh, stronger tissue in a better pattern than before. PRP works on the same idea, but uses a concentrated dose of your own blood's healing platelets. Either way, we aren't putting a foreign substance in. We're using your own biology and giving it a stronger nudge.

Who is a good candidate, and who is not?
Good candidates are in reasonably good overall health with decent nutrition, since that is what the body draws from to heal. Dr. Perrine says it is not a fit for people who smoke, have uncontrolled diabetes, recent chemotherapy or immunosuppressive medications, or active problems at the injury site. An honest screen is part of her process, and the discovery call exists to determine fit before you spend money.
How long until you are back on the court?
- Ozone: minimal downtime, with most patients returning to play within about a week.
- Prolotherapy and PRP: roughly four weeks for tissue to remodel. Gentle movement is fine, but no court time until cleared.
I always tell people to listen to their body during that window rather than push through pain, since pushing too soon is often what got them injured in the first place.

What happens if you reach out?
It starts with a discovery call rather than an appointment: a no-pressure conversation about her services, pricing and philosophy to see if it is a fit. If it is, the first visit is a full one-hour consult covering health history, prior labs and diagnoses, and a physical exam, before any recommendation. As she puts it, it is not a rush visit, and she wants the full picture before recommending anything. Book a discovery call with Dr. Perrine
Common questions
Is PRP available in San Luis Obispo County?
Yes. Dr. Kendall Perrine, ND, offers PRP, prolotherapy and ozone therapy at Purist Natural Medicine in Arroyo Grande, so there is no need to travel to Los Angeles or the Bay Area for regenerative treatment.
Should I try physical therapy before regenerative treatment?
Often yes. Many injuries resolve completely with physical therapy, and how you responded to it is diagnostic. Dr. Perrine specifically asks whether PT helped partially, because a partial response suggests tissue damage that strengthening alone cannot reach.
How much does regenerative treatment cost?
Pricing depends on the treatment and the number of sessions, with courses running 1 to 10 sessions by severity. Specifics are covered on the discovery call.
Can I keep playing pickleball while I have a nagging injury?
Dr. Perrine's rule: normal soreness is fine to play through, but sharp, stabbing or limiting pain is not, and that is the line that turns a minor issue into a real injury. When in doubt, get it looked at and modify play. See our full guide: Read more
