Itchy bumps, weakness and tingling in arms.

Patient: So I’ve been feeling weak on and off. I doubt it’s the flu either, I have no fever, sore throat or anything. The only thing that has affected me is nasal allergies, I’m not sure if the nasal allergies contributed to me feeling weak but yesterday my fingers started twitching and my arms started feeling tingling. What could be the problem? I also have some small itchy bumps, they look nothing rashes, just itchy bumps. Please help.
