Lumps at injection site 4 weeks after FUE transplant. Is this Normal

It is best to contact your surgeon for post surgery issues and care.You may have a scar or even a hematoma.

Thank you for posting this question. If they are rock hard and persistent 4 weeks after surgery, it's quite possible that it's a hematoma. It's quite uncommon, however. These typically resolve in the weeks following surgery, so some more watchful waiting may be in store, but I would certainly return to see your surgeon and be evaluated in person.

I would certainly followup with your physician. You may have a hematoma needing to be drained. Usually the swelling from the anesthetic goes away within a few hours only to be replaced by the swelling from the surgery on the 3-4th day. But I would expect that to resolve within 1 week. 

It looks like your surgeon performed a nerve block.  The lumps may be due to bleeding after the injection (especially if the area looked bruised after surgery); they could be clotted blood.  Typically this resolves in a few weeks as the clot liquefies.  It is unusual, and a visit to your surgeon would be a good idea to have it evaluated in person. 

I never do nerve blocks; however, I suspect that you have developed two hematomas (blood filled area) which should go away with heat treatments but if they don't it may be an encapsulated hematoma.  Please return to see your surgeon
