I previously shared some tips for managing sickle cell. If you found those useful, I have a few more suggestions that also may help.
I find that when I am in pain, balms such as Mentholatum Deep Heat help. Balms that contain ingredients such as menthol and methyl salicylate are counterirritants and have pain-relieving properties. Once applied, the change in temperature triggers the dilation of blood vessels and promotes blood flow. Balms can also distract from the feeling of pain.
