Hello,
You had a sebaceous cyst on your back removed by minor surgery. Presently, it is fine but you are experiencing pins and needles in the hand they injected
anesthesia to knock you off. Do continue to take antibiotics and analgesics that you have been prescribed by your treating doctor. Get the wound cleaned and dressed every alternate day for faster and better healing.
Pins and needles that you are experiencing is because the
nerve injury due to prick by injection. You are suggested to get it clinically examined, if the injury is deep you may require treatment so that it does not cause long term complications like being unable to work, RSD (reflex sympathetic disorder), or complex regional pain, etc.
You may be referred to a
neurologist for further management. In the mean time take diet rich in vitamin B6, B12,
folate to help repair the damaged nerve. You can also take supplements. Apply ointment
Soframycin on the affected area for relieve. Stay away from addictions if any.
.
Take care. Hope I have answered your question. Let me know if I can assist you further.

Dr. Nupur K., General & Family Physician
