When I’m active my hands get hot and veins in forearm feel like they’re going to burst. Please help.

You may have secondary Raynauds, which is often more unique, difficult to treat, and worse than primary. 

I get this too. I don’t think there is much we can do except to move more purposely and in a more relaxed manner, which can be done even if you are exercising vigorously. There are YouTube videos on stretching the hand and fingers that I find helpful. Make sure you’re not dehydrated and you don’t have other conditions, such as tendinitis. 

Could it be erythromelagia? I have it in my hands when I get hot, palms and fingers turn bright red and they burn. It is much less common than Raynaud's phenomenon but when it does occur, it can occur in tandem with Raynaud's.

Suzanne I feel for u I’ve had raynaulds for over 20 years always thought it was from when my fingers got frostbite but that is not the case The cold and if I get excited brings it on and now it takes over a half hour to get feeling in my fingers in the early stages my fingers were just turning white now they go from white to red then purple to black which freaks me out cause I feel like I can be a candidate for having my fingers amputated if I can’t revive them in time Doctors today are not what drs use to be the majority of them just pass the boards by the hair on their chinny chin chin They cannot make a decision on their own without going on the internet and reading about what they think u might have My 24 year old daughter was in hospital for swollen lymph nodes in her groin and dr did biopsy  before he even got results he said the antibiotics we gave u in IV should have shrunk the lymph nodes and since it didn’t u must have lymph node cancer just a thing to tell a 24 year old kid Anyway got the results from lab and lab supervisor said he never ever seen this before so it must be cancer soo anyway they sent biopsy to Mayo Clinic and they said it was an infection and needed correct antibiotic to get rid of infection I don’t trust any doctors anymore and I sure would like to sue hospital and doctors for scarring the s**t out of my daughter and making her feel worse than what she was already sorry for breaking your ears  but I just went off on a tangent

I have the same issue when I work out. My lower arms and hands turn red and are very hot.  My knees, lower legs and feet turn red as well. Because of this, I no longer work out. It has caused humiliation and has caused me to become depressed. I was diagnosed years ago with my only symptoms being extremely cold toes that turn a little red. Eight years later, both my feet are painfully cold  and purple. When they warm up or it’s hot out they are painful swollen and bright red. Last year I noticed my arms and hands were only effected when I worked out. They would turn bright red and felt a burning sensation. Now my hands are always red.  I have no idea what’s next to come. I have an appointment with a cardiologist in March of this year. I am going to speak of all of my symptoms and progression with this disease. I will keep you updated on what the doctor tells me. I completely sympathize with you and do I for the both of us that this disease can get under control. So thankful I had found this site.
