My daughter is away at school and has called me about a red spot that popped up on her arm in the elbow crease. She said she noticed it earlier today. It will change. Sometimes it s a bump (pimple like with no head) and then flatten out. And now she says it s larger than it was. And her arm is tingling both lower and into her shoulder. She had one of the occupational therapists she s is doing clinicals with check it and when they put pressure on the spot it was painful and caused the tingling. The OT also said it looks like her arm is slightly swelled. Any ideas what this could be? Thanks
