Can SPD disappear?

At 20 weeks ish I was diagnosed with SPD pubic pain. Since then I have found it very difficult to do things like steps, putting on socks/ pants, getting in and out the bath/car/bed. Basically anything that involves lifting and separating my legs has been agony.

Tonight I was feeding my sheep, and one foot slipped downhill on the grass as I turned to try and prevent falling on my tummy my legs half did the splits, it was so sore I screamed, but then the pain was gone. I landed quite softly on my bum so baby and I are fine.

Walking back into the house I realised I was no-longer shuffling and I stepped up the steps 2 at a time pre pregnancy style (I have long legs 😂). I no longer have any hip pain....I can lift a leg and shake it all about and everything is fine, I can squat again and reach my feet 😂😂😂😂

I'm confused I thought there was no cure???
