Why do I feel weak in the knees and generally unstable while pregnant?

Why do I feel weak in the knees and generally unstable while pregnant?

Relaxin: Relaxin is a hormone that is released in pregnancy. It relaxes the connective tissue in your joints. This makes them looser and makes you more unstable when you walk or exercise. Relaxin is the reason pregnant women waddle. It is also the reason pregnant women are more likely to dislocate their joints. Take things slowly and use extra support when pregnant. ...Read more

After today's gym session my legs feel weak and my knee gives way sometimes. This is 6 hours after my workout. How long should I feel like this for?

Work out: This may be just a sign that you over did it. Fatigue after a workout is not uncommon. Take some anti-inflammatories, stretch well, and ice your legs. It may be that you hurt more tomorrow than you do today. As long as it is not getting worse, just watch it and decrease your workout intensity until you are back to baseline. Otherwise, see a doctor. ...Read more

Not positive - maybe: Gastroenteritis. See you are a binge eater- were you overextended when you began vomiting. Start with clear liquid like water, soda that is clear, or sports hydration drinks. Sip often to prevent dehydration. Work up to solids with bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy ; high fat foods. Rest. ...Read more

I sat at my desk for hours with my legs crossed under my chair. When i moved my knees hurt on inner side and still feel weak after months. What is it?

Neuropraxia?: Sitting like that can put pressure on the nerve that curles around the top of the fibule, outer small bone, and can lead 2 a compression injury to the peroneal nerve in the leg that is being sat upon. Stop doing it. Recovery is fast or long. Ur's will b long. If this nerve is the culprit, test sensation in the web between great & adjacent toe, if sensation is decreased that's it. ...Read more

Behind my knees, bottom of my butt, and lrgs all together hurt and feel weak. My hips too. Dr says its  tight hamstrings but he didn't do any tests.?

Sounds reasonable: The symptoms alone suggest that the hamstrings are tight. Physical therapy, not just walking, wold be the way, to go. Ask your doctor for a referral. However, if you don't improve, other possible cause such as tendinitis or arthritis need to be considered. ...Read more
