I had this problem however, I replaced the shower head and the pipe (flange?)it attaches to. It was not difficult nor expensive to do and most DIY websites have instructions. Only things you need is some teflon tape and wrench. If water is seeping between the walls, well, your bathroom tiles will start to loosen and fall off or in my case a big water spot appeared on the ceiling in the room below. Good luck! P.S. Taking a bath should be okay if the bathtub faucet is not the same as the shower head faucet - I continued to use bath tub until I got the nerve to install the new shower head.
