When you get injuries
Well nothing earth shattering here, but just thought I would pass on something. If you hang or overstretch manually and at the base you feel sore in a way which is not typical stress and feel like something is wrong then I suggest ice. You penis is not really al that different than the rest of your body in this case. After an injury you use ice. I think some guys are using heat and want to suggest you change to ice. I am not talking about warm up, but on off days if you hurt yourself then use ice.
I am really addressing injuries more to the base and ligs from stress than burst capilaries or injuries from jelqing and ulies and other lateral stresses. If my skin is overstretched from ulies and lateral stress (more irritated and tender than injured) I warm it up (just a tiny bit so it will absorb what I want to apply) and apply vitamin K cream or Vitamin E oil and also arnica.
So I have suggestions for cold. Use the frozen peas (the tiny ones are the best). Only 20 minutes at a time, and wait a couple of hours before you do it again). Also what you can do to make it more bearable is get a t-shirt and wrap the upper part of the penis until only one inch or so at the base is exposed. I also do this because there is no need shrinking the upper shaft where I have stretched it out from wraps and stuff. You can also put a robe or material between your legs and the peas (that way it only hits the base and your body). After 10 minutes turn the bag over to keep the coldest part on the base.
What I am saying is that using cold rather than heat will help you recover faster. I know because I have tried many combos of ice/heat etc.
I also have had sucess with using MSM in capsules and putting the powder in the palm of my hand and a dab of arnica and making a paste and applying. Recently I have used DMSO and not had any irritation or problems. I believe it also has helped. Just be sure to clean the area well because it penetrates the skin and might carry the germs into the body. Also wash your hands afterwards. I bought a roll on applicator.
