Hi, yesterday I woke up with nausea, diarehya, extreme stomaches pains, chills, night sweat, fever, fatigue and this morning with a toothache while the other symptoms are slowly subsiding.the day before I acquired these symptoms I injected myself with a potentially dirty/used syringe. Could this be due to early stages of HIV, hepatitis c or b, or food poisoning? Please, please help. Thanks
