Bone & Muscle problems

I am interested to know about the pelvic area in both males and females. Does anyone know which bones are part of the pelvic girdle? Also, which ones are more prone to injury and fracture? Please note that only I look forward only to well-informed and detailed answers. Thank you!

My mom is having pain from knees to the foot and feeling shortness of breath while walking for long distance.

I am suffering from chronic compartment syndrome in leg. How can I cure it. I play badminton. Will it be okay if I knee caps or ankle caps or it can increase the pain?

From the past 10 days, i have a leg sprain. I tied crape bandage and took pain killer tablets But the swelling didn't go totally and i am getting pain over there

I've been suffering from problems related to my legs pain, Mostly joint, thighs and bottom side of leg with ankle also, from last few days. It gives me a lot of pain to sit and up

I got reddish purple area on tho top of both my feet and occasionaly feel a shooting pain from them

I feel heavy pain in my right shoulder whenever I give little force ( Like when playing tennis or throwing ball with force ). I fell down 20 months back and by that time itself I taken every scan and told everything was fine but there is a sprain. But till now it did not get resolved and when I rotate my hand in some angles I could feel some muscle is moving and I get pain by that moment.

I am now 3 week post op acl surgery,  after first week there is normal swelling, but from last two days there is sudden increase in swelling, I am doing iceing three times a day, till no decrease in swelling, so is it normal or is it sign of deep infection ? The incision and stiches are looking normal (no redness or puss) There is minimum pain while doing excercise only. Does I will have to try medicine to reduce swelling? Or its sign of Injection?
