How long should I try physio before considering injections or surgery?
In the United Kingdom, the standard clinical recommendation is to engage in a structured physiotherapy program for at least twelve weeks before considering more invasive options like steroid injections or surgery. While it is natural to want a quick resolution to joint pain, the biological processes of tissue repair and remodelling take time. Most cases of tendonitis and bursitis respond successfully to conservative management if given an adequate window for healing. Following the NHS-aligned pathway ensures that you avoid the risks of invasive procedures while building the long-term strength necessary to prevent the injury from returning.

The biological timeline of tissue repair
The primary reason for trying physiotherapy for several months is that tendons and bursae heal slowly due to their relatively low blood supply. Tendon remodeling, in particular, is a gradual process where disorganized collagen fibers are slowly replaced by stronger, more aligned tissue. According to NHS information on tendonitis, significant structural changes in a tendon often take three to six months to fully manifest. Rushing toward an injection in the first few weeks may mask the pain but it does not allow this essential biological repair to take place, potentially leaving the joint vulnerable to further injury.
The twelve-week clinical threshold
In most UK primary care settings, a twelve-week period of consistent physiotherapy is used as the benchmark to assess whether a treatment plan is working. During these three months, a physiotherapist will gradually increase the “load” on the joint, moving from gentle mobility work to more intensive strengthening. If a patient has been diligent with their home exercise program and has modified their aggravating activities but still shows no improvement after twelve weeks, a GP or specialist will typically review the diagnosis. This timeframe is supported by NICE clinical standards for musculoskeletal health, which prioritize non-invasive care as the first-line defense.
Identifying a successful or stalled recovery
It is important to understand that “progress” in physiotherapy does not always mean a complete absence of pain within the first month. Instead, clinicians look for functional improvements, such as being able to walk further, sleep better, or lift heavier objects with less discomfort. You should consider your recovery successful if the intensity of your flare-ups is decreasing and your morning stiffness is settling faster. However, if your pain remains at a “red light” level (severe and constant) or if you experience a new loss of muscle power despite three months of effort, it may be time to discuss alternative options with your healthcare provider.
The risks of rushing into invasive treatments
While steroid injections can provide rapid relief, they carry risks that physiotherapy does not. Repeated injections can weaken the tendon fibers and, in the case of bursitis, may occasionally lead to localized skin thinning or infection. Surgery is even more significant, requiring a long period of post-operative recovery and carrying the standard risks of any invasive procedure. By committing to a full course of physiotherapy first, you are giving your body the best chance to heal naturally. Many patients who were originally considered for surgery find that their symptoms resolve entirely once they reach the four-month mark of a dedicated strengthening program.
How the type of injury affects the timeline
The duration you should try physiotherapy can vary slightly depending on the nature of the injury. Acute bursitis, which involves a sudden swelling of the fluid-filled sac, often settles more quickly, sometimes within six to eight weeks of conservative care. Chronic tendonitis (tendinosis), which involves long-term degeneration of the tendon fibers, is much more stubborn and almost always requires the full twelve to sixteen weeks of loading to show results. If you have a long-standing “niggle” that has been present for years, it is realistic to expect that the rehabilitation process will be on the longer end of the clinical spectrum.
When to discuss the next steps with your GP
If you have reached the twelve-week mark and your progress has truly plateaued, the next step is usually a referral for diagnostic imaging, such as an ultrasound or MRI scan. This helps the clinician see if there is a specific structural issue, like a large calcium deposit or a significant tear, that is preventing the physiotherapy from working. In the UK, this evidence-based approach ensures that injections or surgery are only used when they are likely to be effective. Even if you do proceed with an injection, you will still need to continue your physiotherapy afterward to ensure the underlying mechanical cause is addressed.
Conclusion
You should typically commit to at least twelve weeks of consistent physiotherapy before considering injections or surgery for bursitis or tendonitis. This window allows the body’s natural remodeling processes to take effect and ensures that you have exhausted the safest, most effective first-line treatments. While the journey to recovery can be slow, building a strong and resilient joint through exercise is the best way to achieve a permanent, pain-free outcome. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can I have an injection if my pain is too severe to do the exercises?
In some cases, a GP may offer a “window” injection to lower pain levels enough for you to start your physiotherapy, but this is usually a secondary option.
Why does my physio want me to wait twelve weeks?
This timeframe allows enough time for collagen remodeling and muscle strengthening to occur, which are the only ways to structurally improve the joint.
Is it normal to still have some pain after two months of physio?
Yes, it is common to have lingering mild discomfort as you increase the intensity of your exercises; your clinician will monitor this to ensure it stays within safe limits.
What if I can’t afford twelve weeks of private physiotherapy?
You can discuss an NHS referral with your GP, which will provide you with a structured program and the necessary follow-up reviews within the state system.
Will a scan show if I definitely need surgery?
A scan provides a picture of the structure, but it is only one part of the puzzle; your physical symptoms and functional ability are often more important for making a surgical decision.
Does resting for twelve weeks count as trying physiotherapy?
No, physiotherapy is an active process; resting without doing the prescribed strengthening exercises will not rebuild the resilience of your tendon or bursa.
Can I move straight to surgery if I have a complete tendon tear?
Yes, a complete rupture is a different clinical situation and usually requires an urgent surgical referral rather than a long period of physiotherapy.
