Arcoxia for Sciatica treatment

I have been suffering from sciatic inflammation for about 3 weeks. The medication had no effect on my pain. There were stomach aches, lack of drive and difficulties in defecating as side effects. After 3 days I dropped off Arcoxia.

Because of my ankylosing spondylitis, with severe pain in the ISG and radiance in the buttocks, I was prescribed Arcoxia (90mg). I had previously taken irregular dyclofenac retard 75mg for several months, but had to discontinue it because of severe gastric / intestinal side effects. Comparing with Dyclofena, Arcoxia takes longer to work (about 1 hour) and the pain-relieving effect is a bit weaker, but still sufficient for me. Side effect with sporadic ingestion (on average once a week, sometimes even 3 days in a row) not available. No stomach / bowel problems, nothing. After a few months, however, I had to take Arcoxia more often, about 3-4 times a week, 3-4 weeks following. Now more and more common side effects such as sporadic palpitations and stumble. Extrasystoles, strong pulse sensation, sporadic pulse turf. Continued dizziness and dizziness, severe fatigue. Will have to sell Arcoxia well.
