Since Mother's day and walking wooded trails the day before, a tennis ball sized lump developed over the right lateral malleolus. After that had intense Quad, Ham, Gastroc spasms and multiple bruises about quarter to half dollar size. Presently, bruises appear on post forearms. Blood work Neg. for Lyme's. Suspect spider bite venom is systemic, capillary fragility disrupts myofibrils = dysfunction in the contractile action. Thank You Bruce.
