I have studied your case.
You may need MRI to see gor grade of MCL tear
I will advise to
Rest the part and avoid any movements that produce pain.
Apply ice or a cold
pack to the painful area for 15 to 20 minutes, 4 times a day for several days. Wrap the ice or cold pack in a towel.
Till time you can take anti-inflammatory and antibiotic if infection is suspected.
If swelling and bruise
is not reducing and giving pain while I will advise you to further investigate
I will advise you to do MRI and Ultrasound
of the swelling.
Partial tear can be managed conservatively with physiotherapy
with USG and TENS
