i am a 66 year old female who has always had straight hair. After last two hair cuts, it is suddenly naturally curly. Is there a medication or medical condition that you know of that might cause this? Medical info: a month ago, I fractured my left elbow, in hospital, I had TIA episode with no residual effects, and clear CT scans. Also I had a pacemaker replaced before fracture repair. Now post-op I am on gerectics drugs of Plavix, Lipitor, a BP medication and have abdominal injections (Enoxaparin Sodium 40/9.4 mL)I have followup with Neuro and Ortho w/xray in two days. But pain in elbow has intensified and I am a little concerned.
