I am not feeling 'too bad'
I do get tired easily, nap most days.
The one thing that bothers me, is I am trying to move around more each day, but by mid-day, my legs ache. Is that just from lack of movement, exercise the last 3 weeks?
I don't think it's unusual to get tired enough to have aching legs if you are up much. Three weeks sounds longer than it really is for a recovery that takes at least six weeks initially.
If you haven't been doing some walking it would be good to do some but don't push yourself. Your body will tell you when it has had enough. I would say aching legs would be one indication. As you heal your body will get stronger and you should be able to do more.
I can remember standing in the grocery line at 4 wks resting on the handle of the shopping cart, just not able to believe I couldn't do this, but I really couldn't. I should have sent someone else. I wasn't going to carry them into the house so thought I had it covered. Listen to your body and when you are tired or hurt, stop what you're doing.
I hope you continue to heal well.
I agree take your time and dont rush into it all I also get leg cramps I was told sometimes it is just from surgury and in another thread it says to eat banannas milk things like that it might be muscles strecthing
Another thing to consider is how much are you drinking? My legs ache when I don't drink enough and get dehydrated. I also had leg aches that cleared up when I started taking my calcium. Low potassium can also cause legs aches, so eating a couple bananas a day can help there!
Mostly likely it is part of your recovery and should go away on its own soon!
