Hi Fernie,
speaking as a guy who also takes Cialis (tadalafil) daily, I can say that leg and lower-back muscle aches are actually one of the more common side effects, especially in the first couple of weeks. I had a bit of that too when I first started, mostly a dull soreness in my thighs. For me it settled down on its own once my body adjusted, and now everything works really well with no major issues. Some people manage the aches with light stretching, staying well-hydrated, or taking the dose in the evening so they sleep through the worst of it. But if the pain is strong or doesn’t improve after a couple of weeks, it’s worth checking back with the doctor to adjust the dose.
As for pumps, a simple, good-quality vacuum erection device is usually enough - something medically approved rather than the cheap online versions. Many men after RALP use them to support recovery and improve blood flow. A urologist or specialist nurse can give you a proper brand name and size recommendation, because the right fit matters more than anything else.
Hope your husband continues to recover smoothly, you’re both doing everything right so far!
