This calculator helps estimate a safe recovery timeline for common tendon injuries like tennis elbow or Achilles tendonitis.
It considers your injury severity, age, and activity level to guide your return to daily activities or sports.
Use these estimates to plan your rest period and discuss realistic goals with your healthcare provider.

How to Use This Tool
Start by selecting the location of your tendon pain from the dropdown menu. Be specific—pain on the inside of the elbow is different from the outside.
Next, assess your pain level honestly. If you have swelling or pain at rest, select 'Severe'. This ensures the timeline is safe.
Enter your age and typical activity level. If you work a desk job but go to the gym 5 times a week, select 'Active'.
Click 'Estimate Recovery' to see your timeline. Use the 'Reset' button to clear the form for a new calculation.
Formula and Logic
This tool uses a heuristic model based on standard sports medicine recovery guidelines for tendinopathy.
- Base Rest: Starts at 7 days for mild cases, scaling up based on severity.
- Age Factor: Recovery time increases by approximately 1% for every year over age 40.
- Activity Multiplier: High-impact activities require longer rest periods to prevent re-injury.
- Risk Score: A composite score of age, severity, and activity level determines if your recovery is Low, Moderate, or High risk.
Practical Notes
- Ice vs. Heat: Use ice during the 'Rest Phase' to reduce inflammation. Use heat during the 'Rehab Phase' to increase blood flow.
- Cost Considerations: If your pain persists beyond the estimated timeline, consider seeing a physical therapist. Buying resistance bands for rehab is usually cheaper than surgery.
- Unit Conversions: If you measure swelling in centimeters, a difference of 1cm is significant and warrants the 'Severe' classification.
- Time-Saving: Don't skip the rest phase. Returning too early is the #1 cause of chronic tendon issues, which can extend recovery to 6+ months.
Why This Tool Is Useful
Managing a tendon injury is frustrating because the pain often feels disproportionate to the visible injury. This tool helps set realistic expectations so you don't give up too early or push too hard.
It provides a structured framework for everyday people to track their recovery without needing a medical degree, helping you make better decisions about your daily routine and exercise habits.
Frequently Asked Questions
Can I exercise other parts of my body?
Yes, as long as it doesn't aggravate the injured tendon. For example, if you have Tennis Elbow, you can usually still run or do leg exercises.
What if the pain doesn't go away after the estimated time?
If you reach the end of the timeline with no improvement, extend the rest phase by another week. If pain persists, consult a medical professional for a cortisone injection or physical therapy.
Is it safe to stretch during the rest phase?
No. During the 'Rest Phase' listed in the results, you should avoid stretching the affected area to allow micro-tears to begin healing. Stretching begins in the 'Rehab Phase'.
Additional Guidance
Tendon injuries are cumulative. They are often caused by repetitive strain over weeks or months, not a single event. Changing your ergonomics at work or adjusting your sports technique is just as important as the rest period.
Consider using a brace or tape during the transition from Rest to Rehab phases. This adds external support while your tendon regains strength. Stay hydrated and ensure adequate protein intake, as tendons require nutrients to repair collagen structures.
