I would suggest taking some MSM - you can post and verify with Mrs D for interactions and safety.
or use the interaction checkers in the sticky here- I'm sure i posted them here as well as the TOS forum.

It is a version or in the family of sulfur but doesn't usually cause any allergic reactions like sulfur medicines.

I used to have good links for it but lost them.
I took it regularly when I had my severe RSI and also again when the RSI/TOS showed up 2 yrs later- but have been lax about taking most of my vits and supplements since the kitchen remodel - just got out of the habit - since everything was moved around.

Supposedly it it good for so many body and cell functions- and it did make my nails grow and my hair texture was much smoother- I have thick coarse hair.
