Considering Raynaud's Medication - Need Advice

did these help your circulation? I have extreme pain in my fingers, hands and arms. Like they are dying. They have numbness, tingling, pins and needles most of the day now. But the worst symptom of them all is the extreme burning pain. Like someone put me into a fire to burn alive. Ice kinda helps. I notice it starts any temperature over 67⁰ but im in texas where it can be 100⁰ all summer and up to 125⁰. This causes me so much pain I cry and cry. I must take ice cold baths & use icepacks all day. Air conditioner cranked down as low as it will go. Most people complain cold triggers their pain.... but can heat cause pain too or would that be a different diagnosis?
