Bone & Muscle problems

I have been suffering from knee problem from last 6-8 months. I am 54 years old and after x rays doctors have adviced me to go through knee replacement.

I am suffering from severe back pain from last 6 month. Kindly suggest and guide

I'm 16 years old and have been having severe pains in my right hip for nearly a year and in the past few months it has been getting worse. it hurts to walk, run, stand up and lifting my leg to high hurts to so climbing stairs is a struggle.

I have been having pain inside my left ankle ( the bone which is below ankle bone) since last 3 weeks. Doctor suggested me 1 tablet of diclofenac 50mg and 2 tablets of paracetamol 500 mg which I am having 3 times a day. Tablets give me relief from pain and swelling for 6 hours and then pain and swelling come back again. When I lay down on bed then I get relief and it hurts if I sit or stand. My blood reports are normal. X-Ray is normal.

I have undergone c section 4 month before, in some cases such as while standing up after long time sitting and waking up after sleep. I feel leg pain and knee pain. Need suggestion from anyone to recover.

My fingers (on both hands) have recently began clicking more, feeling stiff, and aching. I'm concerned this may be the early signs of arthritis, however as I'm only 32 and have always been in very good heath this surprises me. It started about 1 month ago at the same time as a very stressful event in my life so not sure if stress can be a trigger. Would arthritis begin in both hands at exactly the same time? I have a normal office job so no harsh/repetitive work on my hands. Should I be worried?
