Went to the gym yesterday, was shaking so much afterwards, and the morning after (today) i was fine but now i feel like i'm shaking but i'm not?

Overuse ?: When muscles are overworked, they can become crampy and twitch due to poor local circulation and buildup of lactate in the muscle. Usually a rest period and sometimes massage therapy can restore blood flow and reduce campiness. If you are experiencing tingling or pain or numbness, you need to see a sports med or neurologist to look for causes other than musculoskeletal problems
