Hi and welcome to the Chiari forum.
No.....I do not think u can do this alone....many Drs will tell u that u will need X number of weeks to heal and then u can return to work...it can take more like months...especially if they have not ruled out ALL related conditions as they can affect how u feel and heal post op.
Plus, u can not over do it post op or u will develop set backs.
With the set backs in mind, I am not sure how u can do this without help.
Feel free once u accept my friend request to read my journal on my surgical experience.....Keep in mind we r all different and will have a different experience....having the right Dr, and knowing ALL those related conditions were ruled out is key,
