apparels dressed in formal occasion for maternity ladies

I have been a RBKA since Dec 2014 but due to infections I did not get out of hospital for 5 months. BUT I need to ask - does anyone else get, sometimes unbearable, lower back and hip pain ? I am told the hip pain comes from not having a prosthetic leg for a long period of time and depending on that leg. But is anyone else experiences back and hip pain when walking please give me some pointers to relieve it. apparels dressed in formal occasion for maternity ladies
