I am 49 years old a Male, weight is 235 lbs and I am 6 ,0 tall. I have been experiencing a throbbing pain on the inside of my lower left leg. This has been occurring off and on for the last 2 weeks or so. The pain seems to be increasing. I take Lisinopril 20 MG per day for blood pressure.
It could be muscle spasm. Take painkiller and muscle relaxant like Tablet Diclofenac and Thicolchicoside combination twice a day for 5 days after meals. Apply hot packs. Keep limbs elevated. Get tested for vitamin D levels in your blood. Consume a balanced diet.  Chat Doctor.  Get regular exercise.
