Had cocaine i didn't know was laced with levamosile went to hospital and they gave me double shot of penicillin now i feel worse with back pain?

See your doctor: Levamisol, which is a medicine to combat worm infections used in veterinary medicine, is a very common cutting agent recently for cocaine, for reasons nobody knows. It can wipe out your white blood cells and lead to infections, particularly mouth ulcers. It can also cause an inflammation of blood vessels, called vasculitis, which can effect many organs, including the kidneys. See your doctor asap.
