plantar fasciitis?

I noticed just the slightest feeling of plantar fasciitis when I got out of bed this morning. I have not had PF for many years. A Step class I took (first time in months) on Tuesday may have been the cause. I'll have to pay close attention to my foot now and maybe add some stretches like I used to do. I've been noticing it a tiny bit during the day today too.
