When you have any auto immune illness the most basic Doctor you should have as part of your team is the Rheumatologist. He should be like the ring leader if you can find decent doctors....than depending on how your disease is affecting you body you will get other specialist and you should have a just a general GP or Internist Doctor for when you get regular sick.
For example, I had my RA doctor, Dermatologist, Eye Doctor, Endocrine, Urologist(kidney), Podiatrist since i have Ra in my feet, Now i would include a Pain specialist as well and highly recommend that to anyone in moderate to high pain levels. I would also see other specialist doctors as needed such a gastrologist for stomach issues...and as a woman my Ob Gyn of course. But you could have all different kind of specialist just depending on the disease you have, pill side effects etc. Yes, it can get overwhelming but if your Ra Doctor and all the rest all work together. I mean they actually either send letters or speak to one another about your disease and together try to figure out with you a plan to keep you your healthiest it is not as bad as it sounds. You should be seeing your Ra Doctor around every 3 months unless you are doing exceptional well and really not needing a lot of other Doctors than every 6 months.
Do not ever accept that a RA doctor can handle all your different needs that are going on in your body. It is one thing if you are either doing extremely well or in remission but if you are having different issues and your Ra doctor is not dealing with them quickly than insist on seeing a specialist in that area. Such as getting your thryoid pills balance clearly an Endocrinologist will have more experience in doing just that so see one.
If your Ra is decent Doctor he will not let his ego get involved and gladly send you to someone that can be more efficient at helping you.
Since you are seeing 4 plus different Doctors now....hopefully one of them is a really great match with you...one that really listens and gets what you need better than the rest.(if all 4 are great than you can forget what i am going to say) I would speak to that Doctor that meshes with you and ask him to recommend other specialist like him, his personality. Once you have a team that main priority is getting you as well as possible and treats you with respect etc...it really makes going to the Doctor a whole lot easier. They will work together to try and minimize your visits as much as possible plus pills and than taking pills due to side effects. They just really work hard for your best health.
if right now you do not really like any of them....you can take the best of these and see if he can refer you still and say what you are looking fore exactly in a doctor. I personally like to be treated as a partner in that they treat me with respect and allow me to make the final decision on my care. But getting the best doctors for you is the key.
I had all that ...than moved and now i am in medical nightmare trying to find decent doctors. I have no Ra doctors in my area and one i was seeing i finally had to say enough is enough when he lost all my teeth because he would prescribe the drug my dentist kept asking him too. When he finally said okay, it was too late. That was it for trust with him and I worried constantly that next i might lose my eye sight or kidneys because he is not testing those not even half as often as my other doctors were...and the issues are still there .
So do not do as I did and settle for just any old RA doctor...they are like the team leader and if they just treat you so so than odds are somewhere eventually you will pay with your health.
Also if you have a good RA doctor he should be able to put all the pieces together and see how they are related...there are so many autoimmune diseases out there now that they know the names of it is ridiculously high. That is his job to know all these different diseases...not just deal with arthritis. 30 years ago when i first was having symptoms....and then they did diagnose SLE , there were hardly any RA doctors out there. I was in the SF bay area and Kaiser will pull in specialist outside of kaiser if they do not have them ....they could not find one for me. Thankfully, I was working in Sacramento area and they had one older doctor there. He was the best and than my internist's husband became one because she told him what a shortage there was and how hard a time i was having in finding a decent RA doctor. The one in Sac was due to retire in few years...so my friend the internist her husband became my RA Doctor. I was really lucky.
I really wish they had Kaiser up here where I live now...but I was one of the lucky people in that my internist was excellent and from her she would recommend like doctors as herself...so like i said i ended up with just a great team. I greatly miss working with them after my experiences up here. My health has suffered greatly for it despite me trying to be proactive as possible...just the good doctors do not live up or around here.
Hope i helped a little bit...sorry i get wordy...i just know first hand how having 4 or more doctors may seem overwhelming but if they all work together and try hard to make you healthy it is so worth it! good luck, lg
