I’ve had a year getting to grips with a nasty case of this. I reckon I’m about 85% better now.
The ice water bottle roll trick is very good. Also, rolling a tennis ball under your foot to massage it.
A night splint made a big difference but it took me a while to get used to wearing it. Do plenty of stretching of the calf and foot – but don’t overdo it, as too much can make it flare up again.
A voltarol gel massage helped as a regular part of things along with ALL of the other stuff.
Paracetamol didn’t work for me. Neither did ibuprofen, but aspirin helped sometimes.
I had a course of dry-needling from a physio, which had immediate benefits for the PF, but it would normally only last a few days, and felt like I’d been walloped with a cricket bat for at least two days after the treatment.
It’s bloody painful. You have my sympathy.
EDIT: Just seen the post above – taping works really well to control pain – really saved me through the worst of it. I’m still using heel inserts, too, and they seem to give a degree of support that helps.
