In the very beggining of my troubles one GP put me on inflammatory meds and it did help the swollen feeling in the balls of my feet, but i didn't continue taking it for very long because of the amount celebrex she wanted me to take, it was 6 a day, 2 x 3 times daily.
One thing i noticed with my dosage of Tramadol slow release, [300 mg x 2, every 12 hours ] i found that my system must have became tolerant to it and i use to back it down to 200 mg for about a week then go back up to 300 mg and it worked again every time.
I know now that 200 mg x 2 Tramadol a day is suppose to be the normal limit, but i took 300 mg for a few years until i was able to reduce them, 200 mg x 2 daily just didn't cut it for me, but i was under the supervision of my neuro whilst taking that amount.
I hope it settles down for you soon.
