yes i have had 2 c-sections and experienced the same for 2 months the first time, and for about a month the second time. i don't mean to alarm you, but sometimes, this is quite common.
if you are unable to move around at all and find it really difficult to handle yourself, or take care of your baby, please tell your doctor about it. i know it is difficult, but you really need to rest a lot. also, pay good attention to your diet, as your body needs all the nutrition to heal and get strong.
