I Have Been Allergic To Unknown Things. I Have Internal

I have been allergic to unknown things. I have internal hives and they welt on my skin when I /bump something. I had years ago about 20 years ago diagnosis of urticaria hives. It feels the same and not matter what I eat or drink I get red blotches and smalls bumps. I also have been losing my hair more than normal.. I am 50 years old and hair loss may be natural but the hive are driving my nuts. I remember the doctor gave ma a steroid last time. I need to see a doctor anyways for Ann al exam and rxrefill,
. Thank you for looking at my notes.
