I had plantar fasciitis in both feet in 2013. I went to my own GP and was subsequently sent to a podiatrist at Armley Health Centre. I saw their head man, Mr Brown who happens to be on the British triathlon support. Looks after the Brownleas etc! I had orthotics made to measure, plus steroid injections from him all on the NHS, free of charge. I didn't have to wait long either. Got seen within 2 weeks. Don't write of the NHS. It doesn't necessarily mean you get better treatment if you paid loads of dosh.
