Kindly decrease  the kilometres and speed of running. Aply ice acks around knees In order to determine the exact cause of swelling , you need to be physically  examined at Bone and Joint Clinic, Sector 31.

you have not described well about your symptoms and concluded a ligament injury by self only....not a good way sir!!! first of all stop running!!! there can be injury to your ligament or menisci or just a periosteal reaction to your weight bearing bones and joints. consult a orthopedician for diagnosis.. and go for physiotherapy rehab.

Not to worry , a commendable initiative by you to keep yourself fit. Totally unsure about your Height/weight ratio.I assume you have started running after quite a long time and wanted to catch up with your previous benchmarks. giving some rest to your feet / legs should do the magic of restoring your walking issue, along with some ICE / Cold pack applied at ankle to alleviate your swelling. Also Assure that you are using right footwear i.e Running shoes shod type (if you have just started running) and not bare feet running (only use once you have trained your self enough).

Avoid running for some days n do strengthening exercise to the knee muscles....do strengthening exercise to lower limbs
