I have had severe right leg pain from my foot all the way up to my right buttock. i see a neurologist on 10 november but thats not soon enough. i am in a lot of pain right now?

Typical sciatica due to spine disease vs. piriformis syndrome. When on your back if you can raise your right leg up 90 degrees without causing the pain, piriformis syndrome is likely. When waiting for appointment, you can take ibuprofen OTC 200 mg x 2 with food q 6 hours as needed and do leg exercise for this syndrome (you can google the method). Ibuprofen can still be used for typical sciatica.
