"i have been using the fentanyl 75mg patches for 2 months after gradual increase from 25 to 50 to 75mg changed every 72 hours, i have degenerative bone in my cervical spine and i am having tests for inflammatory arthritis (rheumatoid). i do notice the pain coming back on the third day - a few hours before i need to change it. the sweating on the first day i awake and the dry mouth are not pleasant at all but a small price to pay for better quality of life. i have gone from active horse owner and working to being on disability. i was in so much pain i was having days of work and many days unable to get up. i am unable to do my horse any more but i don&#039;t feel as much pain and that is what counts."
