Bone & Muscle problems

About 2 months ago I started having severe pain in/on/around my coccyx. When I get up from sitting or laying down it feels like something heavy and painful is pulling down. I've had no trauma to the area, and I am a healthy person. I've been taking paracetamol and ibuprofen but nothing takes the pain away during sitting/laying/getting up although it's perfectly fine while I'm walking.

I am 24 and 50 kg. So highly underweight. Want to gain muscles without going to gym. Can you please suggest me some ways/exercises and relevant diet to gain weight. I have been underweight all my life. And I also have digestive disorders like stool formation problems e.g., (1) sausage-shaped but lumpy, (2) like a sausage but with cracks on surface, (3) soft blobs with clear cut edges (4) fluffy pieces with rugged edges, a mushy stool , and sometimes (5) the ideal stool- like a sausage or snake, smooth and soft. I have to pass stool 2-4 times a day. The other problems are IBS- inflammatory sensation while passing stool, malabsorption, lactose intolerance, gas formation and farting with burning sensation after eating chana daal, rajma, milk products except curd and ghee, non-celiac Gluten sensitivity, restless leg syndrome, spinal pain when sitting without back support, hair loss and whitening.

My dad had an accident and as per the CT scan there is chip fracture in the femur neck.  Initial recommendation is to insert screw  across the fracture.. Need information about orthopedic surgeon in Guwahati for the operation..

I tore my meniscus about a year ago. My knee has been giving me problems. MRI showed internal dereangment of the knee but the specialist I was sent to refused to do anything. Now my knee for the past 2 weeks my knee has been locking up, and giving out. Everytime I move my knee you can feel and hear it click and pop. The pain is getting worse not quite unbearable yet. I'd say on a 1-10 scale 1 being no pain and 10 being the worst I would say 7 1/2 to 8. I've been talking over the counter pain relievers and I have a compression brace on it. And I have iced it and elevated it. None of these things seem to be helping. What should I do?

I am facing severe back ache on the right side till the toe. There is swelling at times. Kindly recommend the solution. Regards
