I have gone through your query regarding multiple nasal surgeries and even you are not free from nasal problems and you have associated pain in both lower limbs
, it is very surprising that you feel relief in your legs by cleaning your nose by succession.
In this connection I request you to send us about your detailed information of clinical findings of your nose and detailed neurological findings along with operative detailes of nasal surgeries already performed on you.
M.R.I. of brain &sinuses
are also requested to understand your problem.
