#Tendinosis refers to the hardening, thickening, and scarring of the tendons, the tough, fibrous cords that attach muscles to bones. This causes pain and a loss of flexibility in the joint. Common symptoms of tendinosis are localized burning pain and swelling around the tendon, pain that gets worse during and after the activity, stiffness in the joint, restricted joint movement, and pain that persists for several months. If left untreated, tendinosis can lead to ruptured tendons so early treatment is crucial. Consult a doctor if you have been experiencing the above-mentioned symptoms for diagnosis and timely treatment.
