[|AI|]  Brief Answer:Ankle sprain requiring cast to reduce movement of ankleDetailed Answer:Warm Welcome. I appreciate your trust in Chat Doctor and assure you are on best portal on the globe for expert online medical services. I have thoroughly reviewed health query you raised, and well realize all of those concerns. Being your physician, I will take care all of them today and will extend my expertise to solve the problems. Based on what you said, it can be said with fair certainty that you have an ankle sprain. It has caused your ankle to swell up. There is a slight chance of ankle ligament tear and does not come up on x-ray. It requires an MRI scan. To be on safe side, you may require a cast on ankle for 2 weeks to prevent it from mobilization. Ball like growth is nothing but inflammation. Hope I ad Chat Doctor.  Let me know if you have further questions. I will be more than happy to clear any doubts. Keep a follow-up to see how you're doing. Regards!
