I would mention my kidney concern to the rheumy on Monday. Perhaps he can go ahead and draw the extra vial of blood or whatever it takes to satisfy your concerns.
That said, it could be from Lupus, from MTX, or from something he did. It's really hard to tell with these things. If it does indeed spasm, that probably is something for the family doc.
Have him lie flat on the floor with feet on footstool. If that doesn't release the spasm, try putting a rolled up towel under him right where the spin is. Or under him left to right just under the underarms - mid back. Also a warm Epson salt bath may help.
