Hi Paul I suffered a TPF type IV in March. Sleeping was difficult but purchased a bean bag to help elevate the leg in bed and found this the best way to get comfy. I am still not working due to pain in the knee and swelling but physio exercises done every day. This is also helping my mobility, I walk sometimes with a stick for support but it is so frustrating not being able to do things you previously took for granted. Try to keep the foot moving if possible, don’t give up you will get there eventually. I am learning there is no quick fix for this so going with the flown. I like you sustained this whilst riding my motorbike home from work and it was no fault of mine that I was knocked off. Could be worse…..at least I can offer some guidance to another sufferer!!!
