Exercices and back pain

My maind symptoms are not back or were back pain BUT, ones i got back to exercices, after absworkout (some of the exercices) and deadlift with light weight kinda give me back pain when i`m doing the exercices or after, i guess this is normal?

i`m a swimmer as well at the biggining when i returned to it, my leg hurts when i was doing breastrokes hurts, not anymore and i did nothing i just go on swiming, still i want to ask about deadlift and abs exercices. thanks.
