Read the side effects from long term use of predi THAT should scare you and those are certainties. Okay I am a statistician at the root of things, We design models for a number of things, in my academic world including drugs etc. do statistical analysis of results of assorted studies including setting up and analyzing the beta testing of most Microsoft business/technical software.
You are getting way too much information from the internet (I suppose including this) of the three classes of drugs used to treat ANY form of arthritis: Corticosteroids,DMRDS, NSAIDS, and Biologicals. The biologicals have by far the fewest long term permanent or serious side effects. The worst are the steroids (what you are taking) followed by NSAIDS.
My guess is much of the misinformation about treatment from these diseases comes from the same groups of people we come in contact with every day, you know the ones who don't seem to think you are sick, or say oh yeah my Grandma had some arthritis.... You know I heard if you quit eating tomatoes and take a spoonful of Cayanne pepper after rubbing the sore spots with Castor Oil, it gets better... But he real misinformation comes from people selling Cayenne pepper pills and castor oil. They go after the NEW drugs because its a little harder to spread fear about something like Plaqunel or sulfazine or even MTX that has been around for 50 year or so.
There are at least 100 BIG companies (and hundreds of smaller ones) out there who's sole job is to plant posts, reviews, opinions etc. around the internet. Then there are companies like one of my old college roomates is find those posts and plant counter posts and "likes" on facebook and build organic search data for U tube. (its no accident when a commercial video goes viral....)
We have had a couple show up here, the founders take care of them really quick.
So talk to your Doc or Pharmacist some one who has had 12 years of education to to do what they do as opposed to an opinion, or self educated researcher, holistic practitioner, ND, etc. Don't trust statistics with out a two tailed regression (and a bunch more) A good example is the "cancer fear" from biologics. Yup a pretty good share of folks taking Enbrel get cancer. Only problem is they actually get it LESS than people who don't take Enbrel. Granted the occurence of a particular type of cancer is higher than rest of the population, but people on Enbrel get cancer the same or less often than everyone else. There is NO evidence that its enbrel and not PsA....
If you want to take your Enbrel but are just a little scared, heres what I would do: Take two field trips.
Trip One: An assisted living facility (a bigger one) Arrive ONE hour before dinner. Watch the residents arrive from their rooms or day room, some pushed in chairs by the aids, some shuffling along, some pushing a walker, etc. Note the hands, humps in the back, the ones bent-over, the ones who can only drag their feet etc, Also note they aren't senile. they will be talking about dinner massing at the door waiting to be seated. They may talk about the 1st graders that came over to sing for them, and Bingo with the Ladies group coming on Thursday, and what happened on days of our Lives today.
Trip Two: go to a higher end Senior Citizens complex. TWO hours before dinner. Watch the residents arrive fro the golf course, shopping, the bridge room, aerobics, Wii Club etc rushing to their apartments to get changed and back down stairs for wine before dinner. Listen to their conversation. Don't miss the innuendo or blue pill jokes, Note the group planning for the symphony or the other planning on seeing the stone 50th anniversary tour of the stones
Realize both groups are the same age, no less mentally able. BUT a huge difference in attitude and physical ability. One group has been overtaken by their arthritis one has not.
Now go home pull out that vial of Enbrel and decide which group you want to be in. If you want to be in group one put it back in the fridge. Group 2: use it.
