Lumps appeared after PDO threads 10 days post?

Dear deathrow1,
Thank you for your question. I am sorry to hear about your experience.
In the absence of photos, and not knowing what threads you have had, and their direction, I can only offer you general comments. I do agree it is good for you to see your doctor for a post treatment review.
Skin irregularities, and bruises can occur after PDO threads, and are temporary. So rest assured.
I have included common side effects of threadlift for your benefit.
What to expect after threadlift?

Feeling of the thread tips poking at your skin. REMEDY is to just massage it so as to help the thread sink in.Skin irrgularities may occur temporarily. Because whereas before you had a (sagging) but smooth flat skin, you now have lifted, but potentially with some depressions on it.Feeling of soft tissue slightly bunched up under your skin. Not visually but palpable area of firmness.Threads can snap, especially on extreme muscle movement, but this would not create unevenness.The first time you do the procedure, swelling and skin changes may some time to settle. With subsequent treatments, the healing process/time gets much shorter.Post care, try to be gentle when cleansing your face. No forceful scrubbing motions downwards.
I hope this helps.

It can take a few weeks for swelling to go after a thread lift procedure. However, bruising and irregularities in the skin can be side-effects of this treatment, and should resolve with time. If you have any further concerns, I would contact your surgeon. Best of luck.

With PDO thread lifting the bruising can cause more inflammation than a usual bruising and it will take more days to resolve. With your description, I think this can be a possible reason why you see these "lumps". You should have  a follow up appointment where your physician will evaluate the skin,  inflammation, thread tension etc. I hope this helps. Dr. L.M.
