My back hurts

My back really hurts and I just can't come up with the right pill cocktail. I have a pharmacy to choose to from (there are lots of colors) but nothing works. Of course we know it’s all my sisters fault. She made me move a huge couch off the fourth floor yesterday. It had been there for over a month and finally my sister gave in to the complaining children and made me move it. I think my sister is tampering with my pills; she's just replacing them with colorful sugar pills. No fun
