I am a 33 years old female, 5 foot 5 inches, weighing around 118-120 pounds. Although I do sometimes bruise easily from impact to limbs , I have a concern about bruising that was caused by attempting to donate blood to the local blood bank. (my first attempt ever) The technician that tried to stick me failed repeatedly and had her supervisor to come adjust. The supervisor accessed the vein on the first try but said it was too late since I was already bruised -she could tell both from feeling the nearby skin and from my discomfort- and said to discontinue the donation. I used a cold pack that day to try and prevent the bruise from getting too big. But returned to the blood bank 48 hrs later since I had started experiencing some intermittent tingling in my hand and forearm below the inner elbow donation site. They gave me heat packs that I have used each evening before going to bed and said to take pain relief (Ibuprofen) every 4-6 hrs for the discomfort -I got a 2nd opinion from my own physician s nurse who said aspirin might be more effective and that the tingling could be normal for a couple days. I am wondering how long the tingling is normal and whether I might have a clot in my arm or not. It has now been just over 3 and a half days since the bruising incident and I still have intermittent hand and forearm tingling.
