You appear to have had either acute viraemia or a acute urticarial attack due to allergy.In case of viraemia ,the symptoms later could be due to post viral syndrome
which can include joint and body pains,diarrhea,abdominal cramps and tingling.The other possibility of a food or environmental allergy
may also give rise to similar symptoms,if superadded on connective tissue
disorders it could be difficult to diagnose.Opinions of a Rheumatologist
,a immunologist or Allergist and a infectious diseases doctor will probably help.
