Hi, Im sorry to bother you but I have fpund a lump on the inside of my right forarm. It is about the size of a pea and hard. My arm keeps going tingley - simular to having your blood taken and the doc releasing the band and the blood rushing back. My arm looks slightly swollen and I can see slight brusing - however I havent bashed it at all. Could you please give any info? Kind regards Louise
Welcome to Chat Doctor .1. The history suggest a painless lump in forearm - if it is at the joint place the possible cause will be ganglia which are seen after a mild trauma or inflammatory reaction.  2. Which needs to monitor, if symptomatic needs a small incision and Chat Doctor. 3. If the lump seen in the middle of the arm in the muscle area - it could be lipoma - fat containing lesion.4. Needs to confirm with ultrasound in both case and a needle sample will be taken if necessary.5. Excision is treatment of choice if symptomatic. Good luck. Hope it helps you. Wish you a good health. Anything to ask ? Do not hesitate. Thank you.
