<s>[INST] My calf muscle spasms and will go into a severe cramp if I point my toes. This has been going on now for a few years and has worsened. My hamstring now does it. This in my right leg.. my right leg now looks much skinnier then my left. What could this be from and what are my options of treatment? [/INST] Hi, Thanks for your query. After going through your suffering, it seems you have developed muscle spasm (cramp). The cramps are caused by hyper excitability of the nerves that stimulate the muscles.  Chat Doctor.  A simple way to prevent cramp is-1. Warm up and stretch your calf muscles before running stretch your calf muscle before going to field 3-4 times and each time holding for 10-15 seconds. 2. Talk to qualified trainer for proper running form and footwear.3. You may run in a heel-toe pattern and avoid letting the balls of your feet hit the ground first.4. Stay properly HY </s>
