No, you aren't alone. For the first 3 weeks I was in a pattern! Day 1 pushed it too hard, day 2 pain meds and rest, day 3 back to manageable - rinse, repeat. I hit 4 weeks last Thursday and this is the first string of days I've felt...
Good luck to you. I'm 3 weeks post op today - no complications whatsoever. You are very wise to take so much time off. My only problem is my inability to sit still. It will all be over soon!
