Bone & Muscle problems

I am having some intense pain in my tail bone for last two days. It's sudden and hurts on sitting down. It hurts when I touch down at rhe area. What could cause it.

Exactly 80 days before I had a distal radius surgery . I am doing excercises to regain my range of motion and attending physiotherapy also but I am afraid of my hand . Now also I couldn't able to do full pronation and supernation, flexion also. It's very slow .I couldn't able to find improvement in this.why this happening to me. Is this normal case? How to regain full range of motion . Is there any specific excercises ? How many times in a day should I do? Please sir I need to know answers for this questions. Please don't hesitate and don't ask for personal consultation. Tq

My father who is 64 years old is suffering from lower back pain which was intermittent initially and appeared like some form of ligament tear of muscle strain pain thst comes suddenly on getting up or bending down to pick something. However over a past year or so it has somewhat turn to be of a chronic situation where he most of the time suffers from the pain.. the pain exactly is not excruciating but however disrupts the normal routine.. he can still drive or do work but feels uncomfortable. His weight is 70 kg and is apparently healthy.. has no history of hypertension, diabetes mellitus or any sort of allergy. He stays physically active throughout the day.. What might be the cause?

I am student of class 11 and got an investigatory  project on PIVD( slip disc) and in this we have to interview a doctor. It will be a small talk for 5 to 10 minutes. If any doctor can voluntarily give their 10 minutes it will be a great help.
