Thanks for writing to Healthcare magic,
I have studied your case,
There can be nerve compression leading to buttock pain and chest pain
you may need neurotropic with calcium and vit d supplement.
If required X ray spine.
As you are having generalized body weakness,i will advise to check B12 and vit D3 level in blood.
Are you having hyperacidity
which can cause persistant headache.
Hope I have answered your query. Let me know if I can assist you further.
