Can the drugs Tramadol(Ultram) or Tizanidine(Zanaflex) cause either tinnitus and/or hyperacusis?

I have both tinnitus and hyperacusis and take both Tramadol and Tizanidine. I was wondering if anyone knew if either of these drugs cause either of these conditions?

[Palmettojeff]

I take Zanaflex for back spasms and if i get up after sitting or lying down for a while after taking the tablets, I get ringing in my ears and they feel as if they're fillin up with fluid....i get a stuffy feeling in my ears and temporary hearing loss (not total, but muffled)

I haven't really been able to find any other evidence of this anywhere else...but it always seems to go away after a few minutes.

Best of luck to you!
