The hot water opens the blood vessels and increases the circulation. The fact that I need to keep warm to reduce the pain makes me think a lot of this is from the blood vessels choking up so there has to be a medication that calms down the blood vessels and in turn would increase blood flow to the oxygen starved tissue. I've been reading about Nifedipine. It increases peripheral blood flow. Relaxes blood vessels.
Newer PCs have both USB 3.0 and USB 2.0 ports. If you want your SuperSpeed USB device to perform at top speed, find a USB 3.0 port and connect the device to that port. A SuperSpeed device that is connected a USB 2.0 port, operates at high speed.
Thanks for you explanation. I was also sure that Port fast is an optional feature that need to enable by administrator but some friend made me confuse So Please correct if i am wrong ... 1] So Port Fast is optional feature that can enable as per requriment, Not automatically enable when we run RSTP. 2] Port Fast can be used with STP or PVST.
