It appears that you do have an allergy to something and it possibly could be to your remaining pins.
I would suggest you see your doctor to see if can help you with this.
Best wishes.
Hi releysmom and welcome to the forum
When your sensory nerve ending receptors that sense
pressure, touch, texture , get disrupted and "confused" due to some factors such as NT dysregulation (primary), fluid constriction in close proximity to the receptors, dryness and other factor such presence of a "foreign" substance (secondary) not being able to transmit a known message to the brain, they revert to the default, which is a message of ITCHINESS!!!
The chronic nature of Neurotransmitter imbalance and reaction to metal is therefore the suspected culprit in your Chronic Itchiness.
Are they titanium pins? If they are, there's a 3% + "allergic" type of reaction to titanium.
Energy Medicine treatment is the only effective way to eliminate this.
Look into "Allergy Antidotes" or "NAET" trained Practitioners/Doctors.
I hope this is helpful, however,it's not intended as a substitute for medical advice.
Cheers!
