Patient: I had a flu Jab last October, after one week I had swalling under my left hand where I took the flu jab. after two to three months this swalling of the glands come and go then progress to another two places under the right hand and under the neck. I  did blood test and they were fine but the swalling still. is their any treatment. Doctor: Thanks for your question on HCM. The most common cause for injection site swelling is infection and inflammation of vein (thrombophlebitis). If not properly treated, this can spread to surrounding skin tissue and form large swelling type lesion. The treatment of this is as follows. 1.  Apply ice packs on the swelling. 2. Start anti inflammatory and painkiller drugs. 3. Keep that hand up for reduction of swelling. 4. Apply thrombophobe cream on swelling. It usually takes 4-5 days for resolution.
