Got hep b and mmr vaccine a week ago. have pain radiating down arm to hand. hand feels tight when i squeeze. how long will it last for? is this normal

Not normal,not rare:: It's not normal but vaccines can have serious side effects that can be long-lasting.It's possible the needle hit a nerve.One must weigh risks of vaccines vs. benefits;the risks are often under-rated.See https://tinyurl.com/y56k2tyz re: Hep B vaccine side effects.Re:MMR see https://tinyurl.com/y8p638hu and https://tinyurl.com/yy7d6fy6 The MMR is 3 vaccines in 1,getting a 4th at same time is unwise.
