Hi all. Last two times I have SI (i usually do it weekly) I have hit a vein and had quite a but of blood come out after taking the needle out. I also then get a hard lump and a bad bruise that lasts weeks. Do you think this is just an unhappy coincidence or something else? I have not changed anything. The only thing I can think of is that I have lost a few pounds in weight on the Keto diet and been working out more than usual. Any ideas?
