PDO Cog Lift - bruising, swelling, inability to sleep, and now lump

At 36 years of age, I was showing subtly signs of ageing with my jawline being less defined than it once was. I did some research and decided a cog lift might give me the subtle lift I was looking for. I had seen some negative reviews but of course assumed that would never happen to me.
The cog lift procedure itself was excruciatingly painful and I have a high pain threshold. The results were also very anticlimactic with very little visible difference. Then what followed was bruising, swelling and the inability to sleep in any position other than my back due to the pain. It’s been a week and my face is still swollen but to add to it, I now have a lump that gets worse when I smile. I’ve been told to let it settle but this lump is very clearly the thread poking through my cheek and I’m so self conscious about it. I really wish I had never touched my face and I’ll have to wait months and months for this to dissolve. Please avoid making the same mistake as me, don’t get a cog lift because it really isn’t worth it!
