Typical symptoms of a hamstring pull are:
A fierce pain or spasm (twinge) along the span of a hamstring or a particular position on the backside of the thigh. There may be acute sensitivity or muscle spasms in the hamstring muscles with propelling motion and resistance. Pain ordinarily increments when tension is administered to the hamstring pull.
There is the likelihood of sensing minor pain when walking even with a hamstring muscle tear. Yet pain will escalate with an arduous workout. An absolute hamstring muscle rupture creates severe pain even when stationary. A ruptured tissue can clump in the backside of the thigh aggravating more pain specially when the leg is arched.
An ongoing hamstring muscle injury may be noticed as protracted soreness. Pain can be felt while sitting, walking, or escalating.
Curtailed elasticity. You may have rigidness or waning range-of-motion (ROM) because of a hamstring muscle pull. The tautness at the backside of the thigh will hamper flexing the knee or aligning the leg. Your stride may be impeded or a limp can start with tautness, that makes walking discomforting. Muscle spasms can happen with a hamstring pull. This damage can induce the muscle or nerves to react irregularly, and incongruous contractions may circulate to the brain inducing the muscle spasm. Pain can be felt while sitting, inclining or declining.
Bruising and swelling in a hamstring pull happens because of inflamed tissues, which is typical with a more acute hamstring strain. Heat and redness may concur with swelling in acute conditions. There may be a sensation of separation, concavity, or a lump, which atypically happens. Sometimes bruising and discoloration atop the hamstring muscle may emerge instantly, or a few days after an acute hamstring strain.
Audible cracking. A popping feeling at the backside of the thigh can usually be detected, when hamstring muscles tear. Which usually occurs with hefty duress of the hip flexion, when the knee expands (straightens) and it may force you to stumble.
