extreme paranoia about appearance

I've had BDD and OCD for about a year but very recently both disorders have taken a turn for the worse. In this past month, I've suddenly become extremely paranoid about health issues, thinking that any problem with my body will somehow adversely affect my facial appearance. I experience these intrusive thoughts on a daily basis and often feel so anxious that I can't sleep.
Basically, I worry about almost everything - smelling expired foods, using potent cleaning supplies, touching and bumping my face, eating 'contaminated' foods, opening the oven etc.
For instance, the other day I began to experience a very uncomfortable dull ache in one of my legs, probably the result of starting a low-calorie diet and exercise program. I worry that I've done permanent damage to my leg or worse that this leg injury will somehow affect my facial appearance. What if I've caused a bone problem in my leg that will upset my entire skeletal structure and eventually have an adverse effect on my facial bones? It's sounds absurd I know - but is it possible?
I think what triggered this is having cosmetic surgery - especially permanent filler in my face - and feeling that my face and appearance are fragile, unstable.
I've even become paranoid that I'm shrinking in height.
But what makes it infinitely worse is that once I start worrying, I then become paranoid that this worry/anxiety will trigger some sort of reverse placebo effect whereby everything I fear actually happens - my face will actually change, I'll actually shrink etc. This is what I worry about most - I know the power of thought is formidable and that the placebo effect appears in medicine often - e.g. women who think they are pregnant and develop every sign of being pregnant but in fact aren't...
So is it AT ALL possible that a reverse placebo effect could take place and that anxious thoughts about my appearance could actually end up coming true simply because I fear/worry they will? Is there ANY chance?

Thankyou so much

no chance....but there is a chance you can rid of this ocd if you dig deep enough into the underlying anxiety that is being expressed this way....go to therapy..no medications alone, but actual therapy.

I know that it's completely irrational that my face could just suddenly distort. However, as I'm only 20 years old and my face is still gradually changing/maturing, isn't it possible that my negative thoughts could have a small effect on how it changes? Like what if hypothetically I had these fears for the next 10 years or so - don't you think that my face could look slightly different than if I didn't have these worries. Also I'm sure it takes a while after surgery for the face to heal...couldn't negative/paranoid thoughts have an effect on how it heals?

Sorry I really don't mean to be annoying. Obviously I do need help and am seeking it. However, I'm not able to book an appointment with a psychologist for another month and am worried about what might happen in the meantime. This may sound stupid - but I don't want any part of my face to change even by a millimeter.

By the way, thanks so much for your original response. I really appreciate it.
