There really isn’t any way of knowing, different people heal at different rates and the same person can do the same injury twice and heal at different rates. Also impossible to read between the lines of diagnoses, some doctors seem to want to be pessimistic so you’re ready for the worst and happy with 6 weeks if you were told 8, frinstance, others seem to worry about dispiriting you (I was given wildly varying numbers for my hip, from “you’ll be walking normally in 8 weeks” to “10 weeks on crutches” to “you might never recover much mobility” depending on who I asked and how I asked).
Make sure the doctors know exactly what you’re asking, is the best advice I can give you, I wish I’d figured that out faster. Also, it’s a scary question to ask but find out what your worst case scenario is- I had to play very careful with my hip because if it healed badly or rebroke it’d have meant a hip replacement, no ifs or buts, and avoiding that was worth any amount of trouble at the time. But with some injuries it’s much less of a deal if you do it again so there’s less at stake.
Hope you get it sorted.
