Martin,
At three weeks your body is only beginning to repair itself. These are considered very early days of the journey. Recovery can take up to a full year, even longer for some. You have a wound, your flesh was cut. Depending upon the approach used your leg may have been aggressively manipulated in an effort to dislocate your hip. Again, depending upon approach muscles may have been cut, soft tissue was disturbed, there was a lot of trauma to the area. Your bone was sawed and a reamer used to create space for the prosthetic. You experienced a major surgery, an assault to your body and it's now beginning to heal.
I'm not sure if you've been to your post op. If not, please make a list of your questions and concerns for the surgeon or PA. I also think you'd benefit from calling the office of your OS with a list of questions. You repeatedly mention calf pain, but maintain it's been checked. Possibly you need to bring it up again.
Are you taking the prescriptions you mentioned your doctor called in for you on Friday? You said you read the side effects and were afraid. The pharmaceutical companies have to list every possible side effect, it doesn't mean you're going to experience them. You need to get some relief from the pain you're describing. Yesterday Josephine surmised you were under medicated.
Are you following the advice she gave you?
You asked again today if you should have imaging on your calf. You need to discuss this with the office of your OS.
All we can do is suggest what works for the majority of us -
Activity balanced with rest / sleep. Follow the Activity Progression For THR -

Set aside exercising for a later date when you're no longer in pain. It's not necessary anyway -
BIG TIP: Hips actually don't need any exercise to get better. They do a pretty good job of it all on their own if given half a chance. Trouble is, people
don't give them a chance and end up with all sorts of aches and pains and sore spots. All they need is the best therapy which is walking and even then
not to excess.
Take your meds on schedule. If whatever you're taking is not managing your pain well enough - phone the office of your OS.
Ice for 40-60 mins, no less, several times daily. Target 4x daily.
Elevate
Drink lots of water
Eat some protein daily, it helps repair and build healthy tissue.
Get outside regularily. You will feel like less of a patient if you get out to smell the roses, breathe in some fresh air, look up at the blue sky, feel the warmth of the sun, listen to the birds chirping. It will do you good.
This can take some time so try not to focus on every new ache and pain. Most of them are fleeting anyway. And it's wise to measure progress by weeks, not days, or you'll continually be let down.
Chin up...you can do this!
