Hi,
I'm 25 weeks now and at 19 I started getting a hip pain. Gradually it got worse and worse and more and more of my pelvis hurt. I've now been diagnosed with SPD so I would defo get a second opinion.
The waiting time for the nhs physio was ridiculous so when it was at it's worst after several days/nights of unbearable pain and no sleep at all (couldn't lie down, couldn't sit -total nightmare) my husband just insisted we paid to go private.
Expensive but the best money I ever spent! It's not perfect now and I still really feel it if I spend more than 30 mins in the car or I do much sitting/bending/stretching but it is sooooo much better!
Go and get help as soon as you can. Be persistent. Help sooner rather than later can keep it manageable.
I went to the docs the first week I had it, they just said "take paracetamol, come back if it doesn't go, it's probably a trapped nerve". Three weeks later I went back as it was worse and then a different doc said "oh that defo sounds like you have SPD" It might not be "SPD/PGP" according to the doc now but it might be in a couple of weeks!
I really feel for you. It's an awful pain. I didn't know what it was at first and found it really distressing.
I feel so lucky that we have been able to afford to pay to see someone quickly and not have to wait for weeks and weeks on the nhs. It's such an unfair system.
Good luck with it. I hope it's not SPD! But if it is I hope you get some help soon. xx
