[QUOTE="Yourgoes, post: 158712, member: 12795"] Chrome allergies as well as Nickel (from inferior alloys) are causing us to explore other options...like Ti. Now when I say 'sensitivities' I'll be more specific and say there are three categories. 1. Significant and immediate type 1 hypersensitivity or allergy. Obvious. 2. Minor or delayed sensitivity - Harder to spot at first as irritation is felt over longer periods of time and is generally mild at first. First symptom is usually itchiness or tingling and slight redness where the material is contacting the tissue. Also seen reactions to nylon fibers used in crosslinked acrylics. 3. 'Sensitive types' - They say they're experiencing symptoms of ....something.... but no visible evidence or other collaborating data. Perhaps it's a coincidence, but many of them also claim to have Fibromyalgia, which could suggest a neurobiological connection. (Think placebo effect, but in the negative). For these people even grade 4 Ti might not be acceptable. 1&2 are easy to deal with. 3 will make you pull your hair out (if hasn't gone gray and fallen out already) [/QUOTE]
