So i pulled my ligament 5 months ago while deadlifting , it was excruciatingly painful now i don't feel any pain at all but some say that pain may reside but it needs surgery in order to get back at lifting again and also when can i continue lifting?

You don’t say what ligament you “pulled”-were you seen and examined by a doctor? If not, you should be evaluated by an orthopedic surgeon to determine if you need any further treatment, like surgery, and if you can return to weight lifting. You should not do any weight lifting until you are evaluated by the orthopedic surgeon. You may need more testing, like an MRI, to determine what is needed!
