You are on 7.5mg of perc...the larger number that follows indicates the amount of acetiminophen (sp?) If you take 8 per day, that is 60mg..
.
Wrap your legs in ace bandages, it seems to work better than anything else. I am sure the heat would help as well.
There are some natural remedies in my journal if you would like to check it out.
Peace and hang in there
