Knee Injury with other physical ailments? Help and advice

Tweet

I injured my knee about a month ago walking down our set of stairs in our house. I had taken a step down on my right leg and I felt it twist, heard a loud pop and felt immediate pain. The swelling was severe at first but after about 2 weeks it went down. There was also horrible bruising plaguing most of the outter kneecap and behind my leg. I went to the local emergency room and the 1st doctor told me there was most likely an injury to my lateral collateral ligament and was causing surface bleeding just under my skin (thus the horrible bruising) and told me to make an appointment with the local orthopedic, which I did. The orthopedic did absolutely nothing, he just gave me a brace to wear and said he was going to schedule for an MRI exam but I never heard back. I decided that I wanted my medical care to be handled at a military hospital (which I'm used to, and they know my entire medical history since I've been with them since I was 2 years old), which is two hours away from where I live. I went there and my family doctor performed some physical tests and said he had three concerns, that I had torn my lateral meniscus, lateral collateral ligament, and ACL. So I did an x-ray. Now I'm waiting to hear back so I can do another MRI and another orthopedic through them. But here's my question: The swelling and pain have nowhere near subsided. I was told the swelling was due to the fluids trying to heal the ACL but there are times I lose feeling in my foot and my foot swells to 2 or 3 times it's normal size, it turns purple and I have excruciating pain throughout my leg. I've also had spasms on my kneecap since the injury that they gave me muscle relaxers for. But lately, during my numbness/swelling/purple stage, I get stomach aches, headaches and nausea. Is there a chance these symptoms are all related? If not, what's causing the numbness/swelling/purple -ness if it's just healing fluids? I even take my brace off several times a day for long periods of time just to let my leg "breathe" but the pain increases everytime I do that. I'm at a loss of what else to do. Any help would be greatly appreciated.
