There is no cause for concern

Detailed Answer:
Hi
Welcome to Healthcare-Magic
Greetings of the day

Dear Ms XXXX


There is no need to be considered about. As there is no discolouration of affected limb it's unlikely to be vascular injury. There is usually vasoconstriction ( temporary closure of blood vessel supplying the skin) which occurs as reflex secondary to injury sustained. This causes the affected limb to be colder than regular regular limb.

Keep the affected limb covered appropriately.

Do get back to me if you need any further assistance, will be glad to assist you.


Take care

My partner says he s not been feeling well for last few hours. He had stomach cramps and went to bed. He just woke me up and said he had pins and needles all over his body, stomach cramps, was sweating excessively, was breathing heavily and then vomited up some brownish substance with white particles. His temperature dropped to about 34C after vomiting and then he said he was cold and went to lie back in bed under the duvet. What do these symptoms sound like?

Hi Doc, i would like to ask if it s normal that my wife bleeds after first sexual intercourse. I ve read the Hymen broke at first time intercourse. But my concern is that, she is bleeding for almost 3 weeks now from the date of intercourse. Is it normal? She bleeds not that many. Just few drops, it bothers me so much. Thank you.
