I don't think I'm straining just like a sharp muscle pain and I try walking every night to help and it seems to only get worse were I'm at times having a hard time walking or I'm limping
If it's only happening when you use the bathroom it may be because your pushing and its straining a nerve or muscle. I would call your doc to be sure though
I get sharp pains in my thighs, hips, and butt. The doctor told me its nerve pain and that I should try stretching more, and taking warm baths
