Hi I'm 18 And On The Occasion I Will Drink

Hi I'm 18 and on the occasion I will drink a Mikes Hard Blood Orange drink which has 5% alcohol I rarely drink them but do when my older friends are partying so maybe 1-3 times every two weeks I've noticed when I drink just one which is my normal my arms start hurting as if I'm not getting a good blood flow to them can you please tell me what causes this and if I should completely stop drinking them
