Raider ~ I can't address the MRI pictures but I can tell you that realistically you can expect an MCL tear to take 6-8 weeks to heal & although there surely could be other things going on in your knee, the MCL is most likely nowhere near healed yet.
Because I had so many things happen to my knee at the same time I honestly don't know where the sharp pains were coming from - MCL, meniscus, ACL, Baker's cyst but I have heard that sometimes a meniscal tear doesn't show up on an MRI. A good OS might be the best source of interpretation on those pictures. Can you get an OS to read those pictures for you? You mention doctors but not whether they're specialists or not. Wishing you well.
