I think I have plantar fasciitis; would aerobic exercise be too much for me?

For the past two weeks, I've been getting a lot of leg cramps while sleeping.

My right sole hurt so much.

I looked into various things, but I guess

I suspect plantar fasciitis.

Yesterday, I massaged the soles of my feet and my calves, so

It has gotten much better.

I really like cardio too.

So that might be why you developed plantar fasciitis.

But I'm so stressed out because I quit exercising.

I'm thinking of doing it little by little.

Are there any cardio exercises that aren't too strenuous?
