Medication is going to be trail and error sadly, and to add more to the sadly part, takes time too know is it one working and two agreeing with you' it's not a fast process. As for me and sulfasalazine i was only on it for six months or there about's if memory serves, and it did not agree with me at all, and i also got no relieve out of it either. In saying that about the no relieve part, i was only starting to learn/deal with PsA, as in using other things such as the right exercise, cold and heat treatments to help the medication, so abit unfair maybe too say no relieve, plus i was in bad place.
Rheumatologist telling you it's so well treated that you can't tell someone has it. LOL. I don't know about other's but if you seen me getting out of a car, up from a chair, out of bed to name some of the things you'd know something was off. I remember one time going to Spain on holiday's, getting of the plane this old gent asked if i need help. LOL.
My wife enjoyed that one more than me i can tell you.
Should you expect discomfort too be the new norm, i can only answer from my own experiences, and for me i would be happy with only discomfort, pain and not being able too achieve your daily goals is worse for me.
Feeling nauseous i'm lucky this one has give me a miss ;). As for depression, oh boy, i was going too skip that one, as it's an open ended one, with so many different factors. I would be a positive person, but i do tread on the dark edge so to speak, not being able to do certain things because of PsA can bring you down if you let it, also if i'm around negative people, but the later i can do something about quite easily.
Work. Sadly i'm not working anymore, i was a builder and had PsA for a good lot of year's before seeking help, had i sought help sooner would i still be working i don't know. Pity we couldn't go back change things/decissions see if the out come would be different, that play's on my mind alot, but it is what it is. I did retrain, and my friend got me cushy number, sadly it didn't work for me. Try to make things easy for your self in work GS, and try to keep in work, believe me you need work more than work needs you.
Hobbies. I have alway's loved steam trains and i'm a 00 model railway modeler. Has PsA effected my hobby certainly it has, but it hasn't stopped me. Just not able to spend as long at it as i would want. Also there's day's where i'm not able to work on the finer stuff, but the day comes when i'm able to get the finer stuff done. The bonus comes when you can sit listening to the radio with a few beers at the weekend, watch my achievements chug a round the track. Not too mention when the grand children come round, their eye's nearly pop out of their heads :0, so hobbies are worth the effort in my oppinion.
Sorry for the rant GS, good luck and keep work as long as you can.
