Its been more than 2 weeks since implant removal is done.
Was there any infection prior to removal surgery..
If not, antibiotics can be stopped..
Weakness and dullness after almost 2 weeks of surgery and medicines may not be the cause..
You should get yourself evaluated to rule out any other possible infection..
X ray looks fine.. You may start walking non weight bearing with walker support for now.
Since your treating surgeon is the best judge, pls consult him to decide when to start full weight bearing walking..
Pain part will gradually subside.. That may happen due to soft tissue injury and fibrosis following surgical procedure..
Next Steps
You should get some investigations to rule out the infection.. Also, get examined by the doctor clinically for better judgement..
