I’ve been experiencing an itchy crawling sensation on my body recently with no rash or bites or anything. I’ve had this before about 2-3 weeks ago and sometime before that too and it seems to gradually disappear and then return again. I get the itching on my face, scalp, arms and legs. I did go to my doctor and she said it must be an allergy because there’s no sign of anything on my body. Did think it may be caffeine as i previously started to drink it a lot more often, so have took that out my diet but still not sure that is the issue.
