acl replacement surgery

i havent been diagnosed with bad circulation other than reynauds disease by a doctor but my symptoms say it may be wider spread than just that, my hands anf feet are both like ice all the time and even my knees are discolored slightly and quite cold. if i apply pressure the skin my hands feet or Knees it takes a bit longer than people with healthy circulation for the color to return and even then the color is a blue/bright and sometimes blotchy white with red color as well

i also tend to get cramp in my calves and the topside of my forearms, but mostly just my calves and sometimes experience dullness in my hearing (anyone who knows about sound might understand this explination, the lows sound muffled and the highs sound piercing and overal makes it difficult to concentrate on sounds and easily become bother at times from them as well) as well i sometimes have vision abnormailities where light seems to hurt and cause me not to be able to do things like stare at the computer screen for more than a few moments and finally altho my sed-rate is only 9 according to a full blood panel done in early december, ever since i started experiencing the cramps and other things mentioned above i also seem to be suffering from non-inflammetory joint pain in my wrists and fingers.

im 25 and i have no idea what my cholesterol level is because the doc said my triglycerides were too high to measure it the number he gave me was 688 a few months ago. im not the least bit overweight(6'2" 180lbs fairly toned) but am a smoker (down to 3-5 a day now) and take adderall 50mg(20mg 2x a day and a third 10mg dose) a day for severe adult adhd and 1mg of xanax a day(either split .5 2x a day or 1mg at night) for anxiety. i use to be a heavy pot smoker but have nearly cut that out of my life over the past 5 months. also in 2006 i was walking 5-20 miles a day for a few months strait but this past year and this current winter especially i've had basicly no exercise, i currently collect dissability for psychiatric conditions and tend to be anti-social unless i have visitors.

now my concern is this, on wensday jan 30th 2 days from now im going for surgery to repair a possible meniscus tear and a deffinite torn acl in my left knee that was injured on october 30th 2007 and am really worried about the impact the things i mentioned above may have first on a reaction to general anestesia and second how it may affect the recovery and healing of my knee. i'll be having a cadaver acl put in to replace the torn one but im wondering if i should put this off for the time being and focus on trying to heal my circulation, the injury is not hindering my daily activity what so ever. it doesnt hurt, is not swollen, and is stable enough to walk on and even hike with without becoming aggravated. i can jump on the leg by itself as well as twist side to side without fear of loosing stability, i can also go from being on the floor to standing using the injured leg without a problem. does anyone have any experience that could benefit me here? please get back to me as soon as possible, i'll be checking this every so often till the date. thank you in advance
