Pain
"We&#039;ll I have been on this medication for 7 months now. At first it worked well for my pain. Your body has to get used to it . This medication works well for my joint pain in back and knees. It will work for headache also. But these past 2 months I&#039;ve had terrible side effects. I get these stomach pains from hell. I get sick and throw up.  The stomach pain is unbearable . Taking the 18mg. 3xs a day sometimes only able to take 1 a day with food for sure and the stomach pain will come. Also has caused upper respiratory infection 2xs now."
