Medications for back pain
Voltaren gel is not allowed as it is an anti inflammatory and is absorbed though the skin and will have the same effect as Advil on your gut. Although heat often feels good temporarily heat also will not help inflamed muscles in your back. Heat causes the swelling to remain. Cold packs is the only real way to decrease the swelling in the muscles in your back. 20 min on 20 min off.
I have used Kalaya Pain Relief rub pre op and think it might be okay post op - natural ingredients etc. You may want to run it by a nurse before giving it a go... http://www.amazon.ca/Kalaya-Naturals-Ultimate-Pain-120g/dp/B 00D2M4W0M/ref=sr_1_1?ie=UTF8&qid=1446133678&sr=8-1&keywords= kalaya
