<s>[INST] Hi, I have a grade 3 AC joint separation. I m reading that grade 3 is sometimes treatable by a sling. But I also read that the ligaments aren t able to repair themselves. So, how does wearing a sling until the pain is gone do any good? If the ligaments don t repair themselves wont the collar bone just come back out of place once the sling is removed? [/INST] Hello For grade 3 ac joint separation which is symptomatic then you may need surgery after clinical examination. Use ice packs to reduce swelling, inflammation and pain. Physiotherapy with ultrasound and Tens will help you, For early healing you can take Tab Colin [it C] and antioxidant with anti-inflammatory [Tab enzymic plus]. Hope this answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care </s>
