hi welcome to H.C.M.Forum. the doctor you have to consult is the orthopedic surgeon. he can judge the amount of pressure exerted on the nerves. some times the disc prolapse
may be minimal but can cause more pressure on the sciaticnerve, & other nerves. which causes pain.
i advise you to consult an orthopedic surgeon. for diagnosis.
besides i advise you to follow some food restrictions. avoid potato other tubers, tamato, cauliflower, egg , chicken, sea foods for some time and observe the difference.
wishing for immediate recovery.
