Article in English: If your tendonitis isn't going away and hasn't responded very well to rest and basic home care, then see your doctor for a physical examination. Your doctor will assess the severity of your tendonitis, sometimes using diagnostic equipment such as ultrasound or MRI, and give you recommendations. If the tendon has torn away from the bone (ruptured), then a referral to an orthopedic surgeon for surgical repair will be necessary. For less serious situations, rehabilitation and/or steroid injections are often more appropriate.  Most surgeries for severe tendonitis is performed arthroscopically, by inserting a small camera and miniature instruments through small incisions close to joints.  For chronic tendonitis, focused aspiration of scar tissue (FAST) is a minimally invasive surgery that removes scar tissue from the tendon without irritating the healthy tissue. If your tendonitis is a chronic condition, but not particularly serious, then your doctor will likely refer you for rehabilitation, such as physiotherapy. A physical therapist will show you specific and tailored stretches and strengthening exercises for your affected tendon and surrounding musculature. For example, eccentric strengthening — which involves contraction of a muscle/tendon while it's lengthening — is effective in treating chronic tendonitis.. Physical therapy is usually required two to three per week for four to eight weeks to positively impact chronic tendonitis.  Physical therapists can also treat inflamed tendons with therapeutic ultrasound or micro-current, both proven to help relieve inflammation and stimulate healing. Some physical therapists (and other medical professionals) use low-energy light waves (infrared) to decrease inflammation and pain in mild-to-moderate musculoskeletal injuries. If your doctor thinks it's warranted, he may recommend a steroid injection into or near your inflamed tendon. Steroids such as cortisone are very effective at reducing inflammation in a short period of time, which can eliminate pain and restore...
