Hey Andrew, I had RT lateral malleolus ORIF & ligament repair one week after my accident as well, plate 10 small screws, 1 large syndesmotic screw. In splint like you for 2 weeks, then he skipped the removable cast and put me in boot (all doctors different). Then had to wait 7 weeks from that point till 2nd surgery to remove synde screw before I could even PWB. The boot was NOT for walking, only stabalization at this point in my case.
Not sure why your not in knee scooter yet, I was using from day 2. Your surgery worse then mine or doctor's order? When using my knee scooter, leg responded as when elevated.
Swelling = inflammation = pain. My swelling improved significantly at 2 weeks by keeping foot elevated and icing, anti-inflam meds like you. Doc gave me prescription anti-inflam as well as pain meds. Are you taking anti-inflammatory? Help tremendously!! After two weeks, only took pain meds when needed (like 1X daily when getting in shower vs the 8 daily preseribed), but I continued with anti-inflam. pretty much daily, elevation (mainly for discoloration), but need for icing reduced.
Although swelling became a non-issue for me soon after 2 week mark (maybe anti-inflams?) and almost literally no pain when foot elevated, ONCE FOOT DOWN still had bad achy pain within seconds due to those blood flow issues you mentioned. in addition I had much annoying pins & neeedles, burning and red, blue, even purple discoloration. So foot up 100% except when bathing, dressing, bathroom and some unavoidable situations.
I was so frustrated not to be able to sit at my desk or the dinner table. I used walker with a seat as a knee scooter, not as good as the real thing but I coped. So by week 3, couldn't stay in bed or the recliner anymore all day, was going crazy. Reading books & watching TV just not my thing. So started to literally lift my leg up on my desk to work on computer (working on computer helped keep me keep sane). At dinner time I rested leg on the seat of walker. Had to twist back and forth to take bites but liked being able to sit with family.
These sensations most probably will continue till you start weight bearing, then will slowly decline. Can scare the @*#$ out of you at times - after bathing with chair in shower it was almost black when I came out. But it's all normal.
I finally started to walk in book at week 10 from accident and significant improvement on the lowering of the leg issues, still happens but way less. However, WARNING, once weight bearing, your swelling and pain will increase significantely again, and a whole new phase of questions. So be sure to get pain med refills when they put you in boot!! I'm at week 12 and just walked unassisted today. Remember I'm behind due to my 2nd surgery so you may be up and about sooner. You have your youth on your side ;-) I'm 56, was not in good shape and had many other health issues working against me.
It takes hard work and much paitence is needed to get through all this. Never imagined the recovery process would be so tough. Keep your mind busy, get adult coloring book if have to :-), read book, get a tablet, keep in touch with friends and family frequently, have visitors if you can to sit with you for a while, don't be afraid to call doc or his nurse with ques, take one day at a time and don't hesitate to ask for help from friends and family.
This is a great site for support. If you have Facebook, another good support is the page that will show up when you search for "Broken / Ankle / Foot / Leg Recovery - On a Quest for Normal." Join, it's a closed group but another great resource while you recover, you will have many more questions. Just a caution on comparing you healing time to others with same surgery. Some take 8 weeks, some 16 weeks, some lot's longer. So many factors come in to play regarding when. We are each unique and will heal based on our individual situation. Best of luck to you!!
