"i&#039;ve been having all over muscle and joint pain. i tried everything otc and nothing helped. saw a rheumatologist who prescribed diclofenac. the next day my pain was greatly diminished and i was able to use my left arm again! the itching i was experiencing before this medicine has intensified over the past week. don&#039;t know if that&#039;s a side effect. i didn&#039;t take it at all today and the pain is unbearable. calling doctor in the morning."
