Thank you for responding. Actually I stopped a few applications of the foam and it subsided a great deal, I then tried it again and after an application it started to come back, so it seems like this may be the cause.
The literature from Pfizer states:
Blurred vision or other changes in vision; chest pain; decrease of sexual ability or desire ; fast or irregular heartbeat; flushing; headache; lightheadedness ; numbness or tingling of hands, feet, or face; swelling of face, hands, feet, or lower legs; weight gain (rapid)
Just wondering if my scalp is more permeable because of the transplant, at least for now until it heals more.
