I am a double board certified US doctor and I have a different answer for you.
Ibuprofen, as an over the counter medicine, is dosed 1 200 mg pill every 6 hours.
You can add an additional pill own two of the doses, not to exceed 1200 mg a day.
More than that would be a prescription dose.
The first test for lower spine disc problems is MRI.
That is usually sufficient if testing is needed.
Rest alone is no longer adequate for medical care of sciatic.
Even if this resolves, you need a structural exam of the spine
Physical therapy is the mainstay of therapy at this point, and you probably need a course of that regardless of findings.
Standard of care would also suggest that you see an MD of physical medicine and rehabilitation, or an orthopedist, NOT a neurologist. The neurologist is not pursuing a structural diagnosis or treatment, which is the plan needed here.
Find me anytime by request in medical for safe, accurate and up to date answers.
