I had PRP with Acell injections on my scalp 7 days ago with several lymph nodes appearing.

Thank you for your question. It is very difficult to answer your question without examining you. For many  years I have been doing PRP hair injections and It happened ones and resolved within 10-14 days. But you need to make sure that your doctor will see you and give you proper evaluation.

In my opinion, A cell is a foreign protein. It is possible that you had a reaction to the aAcell and your lymph nodes were involved. You should return to your hair loss / PRP expert.PRPHAIRMD.COM 

Definitely go to your doctor to get it looked at.  Acell is made from porcine bladder (pig) and perhaps you are having a reaction to it.  Most likely this is drainage from the PRP and post inflammatory process.
