My left knee has been playing up for some time,I have been to the emergency dept of the hospital, they gave me pain killers, we thought it was gout,but this has been going on now for a month and a half. Could it be heading for a knee replacement op, the pain today was terrible, I cannot get up or dress myself, cannot sit, only comfortable in a lying position. I have been taking voltaren pills, codeine is good for the pain, have taken ibuprofen gel and tablets,I cannot go on anymore, what do you think?
