<s>[INST] I m a 23 year old female. Recently I ve been having my fingers go numb or tingle along with the left arm feeling heavy or cramping. Also horrible neck stiffness and sharp pains and my whole body being sore. My period was also late and not normal. Any idea what could be going on? [/INST] hi,thank you for providing the brief history of you.A Thorough neuromuscular assessment is advised followed by MRI of the cervical spine.As you have stiff neck , neck pain, numbness of hand and fingers it appears to me a more of the pinched nerve symptoms. an MRI should help understand the level of pinching well.Also, undergoing physical therapy like therapeutic ultrasound therapy and TENS therapy should help reduce the inflammation and pain. Also exercises on later stages to improve the strength in the muscles for better stability.in my clinical practice such cases are recommended for physical therapy and they respond well.RegardsJay Indravadan Patel </s>
