We can’t answer the question about the restarting of medications or not. That info needs to come from either your surgeons office or your primary care doctor.
In regards to the heat and swelling, increased pain and redness in your thigh, I would also suggest you contact your surgeons office and discuss this with his nurse or the surgeon himself.
They are better equipped to know what’s normal and not normal post op and your medication questions than we are.
Hope your feeling better soon and your recovery goes smoothly.
