Thanks for choosing HCM,
yes you need to meet your doctor
do you have any swelling over your stomach or hip ?
did you have this kind of sensory loss in the past (like after delivery)?
were you on any medications?
you need to see a neurologist
as you told that you cant afford,go and talk to your family physician
yes you may need to take up some tests
be prepared for that
please dont neglect
and be careful and see there is sensory loss in any other site of your body
you can be given treatment only after clinical examination
hope i answered your query
feel free to contact me for further queries
