Hi Thanks for using HCM.
Pain you are suffering may be due to pressure on your nerve
and not vein. Take pain killer like Tab Tramadol
to relieve your pain, and can take Tab Multivitamins.Topical diclofenac
gel can be applied. Give rest to your hand and dont put pressure on the nerve again for pain. Hope I answered your question. Wish you good health and happy journey. Take care.
