In the U.S. Naproxen is available over-the-counter.
I have used the drug in the past for pain but it doesn't seem to help with my PF.
my daughter is suffering with PF, she too has been prescribed Naproxen with Zapain the next treatment if this fails is `TRAMADOL Which if used short term may help, but you can become addicted to Tramadol so be careful. Try ice wrapped in a towel . Hope you can get some relief soon.
Ps. My daughter has been given a boot to wear
It never helped with any of my pain ether possiblydue to it being unable to get to the legiment affected due to lack of blood flow in that tissue and in joint pain. Indometacin was a little better but a cold foot bath was the only imediate relief.
Gel heel pads solved the problem but took several months for the pain to go and it went as quicklyas it had come, Although the gell heel pads took time they did allow me to get about and walk the dog wearing trainers or walking boots.
