can diclofenac cause stomach upset
Diclofenac side effects. :I have been prescribed Diclofenac 50mg 3 times a day for pain and restricted movement due to frozen shoulder. After 3 days of taking the tablets I started getting stomach pains and diarrhoea, so stopped taking them. On the 4th day the stomach ache lasted all day - not severe but annoying enough to be a nuisance.
