Question: Hey doctor this morning before work I had a blood test done. There was not much pain during it but afterwards I was in a bit of a rush since I had to go to work straight after and in the rush I noticed pain in my left arm where the blood was drawn and on the left side of my chest where I feel my heart beating. I had the blood test about 4 hours ago should I go back to my doctor and get it accessed or will it be something that will pass. The pain in my chest is what is worrying me it's on the left side above my nipple. Could blood have clotted in my heart as a result of me rushing after the blood test is it something I should worry about or see if it passes?

Brief Answer:
Apply thrombophobe ointment.Take tylenol and antacid.

Detailed Answer:
Thanks for chooding HealthcareMagic for your query
Have read your query sir,
Most likely cause is Hematoma blood can leak out of a vein and under the skin during veno punctures. This can cause discomfort and pain and can complicate further collections from that site.However pain in chest and thorax can be very likely due to any other problem like gas or anxiety.
I would suggest you to take an antacid and anti anxiety pill and wait for next 3 to 4 hours.
To be on safe side you can get an ecg done.However i don’t feel its cardiac rather is related to your anxiety.

Just wait and watch for few hours and it should pass away.
For pain at blood drawn site apply OTC ointment thrombophobe and hematoma would settle down in few days.
You can also take a tylenol.
No clotting of blood in heart would lead to maasive cardiac attack and if not treated in 15 minutes would lead to fatality.So its nothing like that.

Hello. I fell and hit my head exactly 2 weeks ago, resulting in a pretty large hematoma. For the most part it has gone away, with just some minor bruising and a small hard lump about the size of a pea left. It is still pretty tender to touch. I've had some minor headaches the last couple of weeks, but no dizziness or loss of conscoiusness. This morning I woke up with a sharp pain in my forehead that lasted about 2 hours, then slowly went away. Do I need to be checked out or is this normal healing for this type of injury?
