Yes, tennis elbow usually does heal with time and proper care. Resting from activities that will worsen the pain, applying cold compresses or ice packs to reduce inflammation, and doing physical therapy exercises are all important steps in healing the injury. Additionally, it's important to make sure you have the right technique while playing pickleball using a lighter paddle, taking regular breaks, and wearing an elbow brace while playing can all help reduce the strain on your arm muscles and make recovery easier. Ultimately, it's best to consult your doctor for more specific advice.
