Biopsy of bald spot on scalp. What can cause this?
Hope everyone is well. I have an autoimmune issue that my rheumatologist is saying is rheumatoid arthritis based upon symptoms. Took over 3 years to get this diagnosis. He also feels that I have fibromyalgia. Well, yesterday I went to my yearly dermatologist and she found a bald spot on my head that looks like I can’t grow hair there anymore. She did a biopsy of it. Man did that needle hurt! I am waiting the results which can take up to 4 weeks. My questions are what can cause this and how long after can I wash my hair again. The spot is still pretty sore. Thank in advance.
