My ds2 had an allergic reaction last week his eyes were really swollen and i had to take him to hospital and they gave me piriton liquid. I thought it was a one off. Today hes been playing in the garden and he keeps rubbing his eyes, theyre a wee bit red and his nose is running a wee bit also. Should i take him to the doctor as i think it might be pollen hes allergic too. Would he get an allergy test or would she just diagnose him with hayfever? Any advice would be appretiated as i dont know much about allergies. TIA
