Are "goosebumps" abnormal 25 days after a hair transplant?

Without seeing the area during your graft placement and now, I can't really tell you if folliculitis is to blame for the redness and bumps at your graft sites.I can tell you that the grafts often stick slightly out of the surface and can take several weeks to flatten. Redness can be a normal part of healing, a sign of folliculitis or infection, or a sign of scarring. If you are seeing your doctor and following instructions, trust that the appearance improves after three months. If the bumps or redness get worse, you lose confidence in your doctor, or just think you would feel better getting a second opinion, you can always consult another hair transplant physician. Good luck. 

If you trusted your doctor to perform surgery on you, why would you not trust your doctor if he/she has examined you and determined it is folliculitis.  The best way to determine what you have is with an examination.  If you are not sure of your doctor's recommendation or assessment, you should see another doctor for a second opinion.

If you have any problems, see your doctor and ask your doctor why you are having the problems. You paid him/her a lot of money, so make them work for it

If you have already seen your doctor, you should follow your doctors advise.  Without a picture or examination from close up, it is impossible to come up with a diagnosis .
