Itchy skin after hot tub use?

Hi all. We have a polyethylene tub we got back in 2020. Over the summer, we didn’t use the tub at all, so I just kept putting a little chlorine in it, and got lazy about testing the water. When we went to use it again, the chemistry was way off - super high ph and super high chlorine levels. I lowered the ph to 7.4, lowered the TA to 90, got the chlorine down to 4ppm. Used it last night and then had itchy bottoms after using it. Any ideas as to what’s going on? Thanks in advance!
 
Nothing really looks awry,
Do you think during the time you were lax your fc fell below minimum for your cya at some point ?
Have you ever purged this tub with Ahhsome?
When was the last purge/drain/refill?
How does the water look?
