Around 6pm this evening I had just got back from a hectic childcare pick up/stressful afternoon of meetings and suddenly had a terrible headache, hives all over my body, felt very irritable and then proceeded to have horrible stomach cramps which sent me straight to my bed. Should I call 111 as I am still feeling ropey, hives have now headed up to my upper body! Not allergic to anything, and nothing environmental has changed either.
