"i have three bulging discs, arthritis, and sciatica in my lower back and also was just recently diagnosed with fibramyalgia. i have been on oxycontin for about a year now, and yes it has been increased about three times within that period of time. i am now on 80mg 4x&#039;s a day. it works great with the pain relief, but it makes me sweat so uncontrollably that i have to keep a fan on my on a constant basis. i am also on about 8 more kinds of medicines, so i&#039;m not sure which ones are causing the dizziness. but when i wake up every morning, i can barely walk, and it takes about 45 minutes for the pain to subside. and then i start the sweating. but i can handle the sweating if it helps me walk so i can keep up with my four year old son. truly a life saver."
