Bone & Muscle problems

I am having pain in right hand shoulder from last 2-3 weeks. I am not able to throw ball faster.

I am having terrible ache in my lower back, at the end of my tailbone. It is concentrated at the point. I used to have this pain sometimes in the past and it used to go away in a day or two. This  time it is persisting for long and it is very intense, I can't sit properly. It won't be possible for me to visit the doctor in the next 2 or 3 days, so till then, is there anything I can do? Thank you.
