Numbness And Swelling After Broken Leg. Need Opinion

In 2008 I had a fall and broke my left leg. Tibia was broken clean across, fibula was fractured as well as ankle. I opted not to have surgery and stayed pretty much in a wheelchair for 6 months. I guess it healed Ok but had occasional numbness and swelling afterward. Recently (2012)an MRI showed I had a partially torn Achilles tendon in my right foot . I wore a boot for 6 weeks, but the swelling never completely went away in that heel. In September 2013 I broke a bone in the same foot by the little toe. I have been wearing a boot, but my left leg has been giving me a lot of numbness, tingling and pins and needles from the extra weight being put on it. To look at it it appears there is a bruise (has been there slightly since the cast came off) in the middle of my chin. The insurance coverage I have only pays for preventative care so I m reluctant to start trying to find answers thru the regular means of doctors. I am frustrated and could use a professional opinion. I understand it will be just that, an opinion since you don t know me or have access to my MRI or x-rays. Thanks.
