Yes, it does make sense to me, I know exactly what you are talking about.
My fingers at times get so bad I can barely type - pressure, movement, and even just trying to rest the hand takes all my concentration because it is so uncomfortable (to put it lightly.) My fingers are a relatively newer problem, my feet went kaput 10 years ago leaving me immobile for about 3 years. The fatigue has been a life-long problem (I had arthritis as a child.)
It stinks when pain is keeping you up at night, but it's sleep that will help make it better for the next day. I would discuss with the doctor to try the least and the lightest amount of medication possible (that makes you sleepy) to start with and go from there. I have the same problem. I was even Rx'd the children's dosage of Zyrtec (allergy med) because the adult version made me too groggy the next day.
If you are not seeing your doctor soon, I would consider calling him and discussing this new problem and seeing if they can move your appt. up sooner to be checked out. At least discuss it over the phone and maybe he can ease your mind to what it is????
I have not been on the meds you mentioned, but on others, I was told to take lots of folic acid and/or a B complex daily. You might want to ask your doctor if this could possibly help with the fatigue. It was not a wonder fix, but there is some improvement when I take it regularly.
Take care and have a great weekend. **
