I'm just over 5 weeks pregnant. In very good health and usually no issues. Today, started having incredibly achey shoulder (more towards my neck), like it's in a permanent spasm, and also have developed a severe, agonising, awful pain in my left buttock. It feels like I've been kicked in the ass 100 times, and when I move a certain way I end up in tears because it's so painful. Anyone any idea what these could be? Pregnancy related possibly? Can't get to docs until Monday (all booked up!), and not sure I can continue in this much pain...
