Bone & Muscle problems

It's been more than a month I am diagnosed with Coccycodynia & Sacroiliatis pain. Doctor asked me to take 3 weeks of bed rest and gave me some medicines and also asked me to sit on donut pillow. It's almost more than a month if I am on bed rest there is not much pain but if I sit or walk for more than 10 mins than pain starts. I have consulted 3 doctors but I am not getting a concrete result. Not able to understand what more precautions should I need as I am working and on medical leave from 1 month. Kindly suggest

I was recently diagnosed with chondromalacia patella. I've been having slight pain in both my knees while climbing stairs for 2 years now and recently it got so painful that I can't climbs stairs at all. I was put on medication and my doctors say no MRI is necessary as of now. My only concern is will it ever go away completely so that I could get back to my activities like I used to? Is there a permanent non surgical cure?
