I hope you got a response from your dr by now.
I use 800mg ibuprofen every 4-6 hrs as needed for acute problems in addition to other meds. Or naproxen sodium (Aleve), I can take around 1500mg a day.
Other things that may help
Epsom salt soak several times a day (I hate soaking so I use magnesium oil)
Rubbing bio freeze or tiger balm on the area a few times a day
TENS unit (can you borrow one)
Corny as it sounds, I like to use binaural beats to help with pain.
From Dr Tennant
1. Take Ibuprofen and Naproxen with another drug which I call a "potentiator", since it makes these pain relievers more "potent".
2. Listed here are the potentiators you should try with ibuprofen or naproxen.
Initially try one of each with ibuprofen or naproxen to find out which is the most effective.
a. Acetaminophen - 1 tablet
b. Excedrin® - 1 tablet
c. Aspirin - 1 tablet
d. Immodium® - 1 tablet **
e. Benadryl® - 1 capsule of 25mg
Caution: If any of these cause you nausea, vomiting, bleeding, or black stools, you must stop them. Take an antacid, milk, or Pepto-bismol if you have nausea. Black stools are caused by internal bleeding, and you will need to consult a doctor if this occurs.
** Immodium® is the trade name for loperamide which is the only opioid drug that is non-prescription. It is sold over- the-counter for treatment of diarrhea although it has pain relieving effects when taken with ibuprofen or naproxen. Too much could possibly cause constipation.
